Hello. I'm looking for a good condition Shankle Heel Toe Kit for a Spica Alfa Romeo as I would like to reverse engineer it. I'm not an engineering company or retailer, just a guy with a 1979 Spider who would like to lower the throttle pedal so I can heel/toe with a little bit of CAD experience and some experience ordering parts from Send Cut Send. I'd be happy to just borrow the part and pay shipping, but if you're looking to sell one I can make that happen as well. Depending on how things go I can envision either just offering the file to be sent to SCS or have a batch made. Not sure yet.

On my alfetta sedan which i no longer have, I had to install the heel/toe kit and then later also a spacer on the brake pedal as it still wasn't in the ideal position. I used a meta OMP brake pedal pad, drilled holes in the metal brake pedal and then used some bolts with nylon spacers to get it to the right height. This is all to say that if there is more space needed than what the heel/toe kit can provide, maybe its just better to space out a brake pad and ignore messing with the linkage.

Your experience may differ, but that is what I had to do to get it right. I did a lot of mountain/canyon runs at speed and it was critical to have the pedals just so.

I actually have the OMP pedal covers on my car and have wanted to add spacer to the brake pedal. I was thinking of 3D printing one but was worried about the strength when pedal force is applied. Some strong nylon spacers should do the trick instead. I also have a second pedal box that I plan on modifying to spread the pedals apart more to accommodate my US size 12 shoes. It would also be possible to change the throttle pedal height while attempting to spread the pedals apart, but the adjustability of the Shankle kit caught my eye. It also looks very simple to recreate. Being 6'2" I am definitely steeped in the not-so-subtle art of getting myself to fit comfortably in my Alfa and I appreciate all tips and tricks I can get. I've got work to do on the seats to lower them and I'm looking at a 360mm wheel to hopefully give me more room for my legs. The list of stuff I've done and plan on doing is actually quite extensive. On top of everything I've removed the sun visors and the arm rests :LOL:. The nice thing is that when you wonder if all of this stuff is really worth it you just have to hop in for a short jaunt and you get the answer unequivocally.

that’s exactly what I did using parts from the hardware store and experimenting. You can see what I did in the photo below.

Made a HUGE difference in how fast I could hustle the car on mountain roads. I’m 6’2” as well, size 11.5 shoe and this worked for me.

the metal is VERY thick on that pedal, took me forever to drill through and that’s why I only used 2 bolts. Was never an issue.

I have a Sankle heel and toe kit I can lend you. I'm not 100% sure whether or not I'll use it on my GTV but I'm about a month away from having it back on the road to try it out. You can have it in the meantime. I won't be able to get to where it's stored until Wednesday but send me a DM with your info and I can send it to you.

Much appreciated. I will DM you my info.

I have a homemade one used on 1971 FI 1750 GTV available. I think Somehow patterned after Shankle kit.

That looks excellent. None of the pictures I've seen of the original have the main arm extension in a position where you can see the tab on the lower section, just one tab on the middle of that arm. The tabs are my biggest concern with it being cut and bent, since the tabs have to have enough height for the machines to be able to "grab onto them", so to speak. The lower tab I get, as it provides a stopping point for the adjustability. Not quite sure what the middle tab is for. I'll find out the reasoning eventually, I'm sure.

Each car is different, but I didn't use the gas pedal as it added more thickness, which took me farther away from the goal. I think i tried no gas pedal cover at all but it was slippery or something -- has been a while. Good luck!

It's too bad that none of the Alfa parts vendors has come up with an updated version of the heel & toe kit. The difficulty of rev-matching downshifts when driving enthusiastically really takes away from the enjoyment of my Spider :(

Knowing the center to center distance of the two parts and looking at pictures should be enough to recreate them. One is an aluminum piece with two holes and one is a flat steel piece with folds for strength. I have two installed on my cars and thought of making some drawings when I had things apart for repairs, etc. I never did. It would be great to have these drawn up and shared. Possibly sent out to Send-Cut-Send for manufacture. I don't think Shankle made any patent on these and they don't exist anymore anyway. Go for it.

I have one on the way from smurdy (who is a legend) which I will use to model and replicate. I definitely lean towards just providing the file and a BOM to have one made if you need it (Send Cut Send can do zinc coating and powdercoating, etc, so a completely finished part should be possible, barring cost), since I am not inclined to get buried in having to deal with investing in an inventory that I have to manage and sell. The implications of copy-engineering a component that was designed by someone else definitely weighs on me, but given that Shankle is good and gone I think it is ok. I also worry a little bit about some company picking up my work and selling it themselves, but not too much because that would result in what we wanted anyway, an alternative option to purchase them new.

Parts have been modeled, tested with my 3D printer, tweaked, and ordered. I have a coolant hose that I'll need to relocate out of the way but amazingly even the 3D printed parts withstood a few cycles of the throttle. The cost for the parts in chromoly steel with powdercoating from Send Cut Send is $36. They should arrive ready to install, no painting or sealing necessary. They could be made in 316 stainless as well, but those came out to below the SCS minimum order, so you'd be paying only $5 less for them anyway. I'll also source the hardware this week so I can get a total cost for anyone who was interested in making one. The idea is that you won't need any tools or paint supplies or anything, you can just submit the files, hit the hardware store, and have everything ready to install.

I’m amazed that 3d printed parts didn’t fail immediately. It seems like this would be subject to a lot of stress. Overall the cost seems very reasonable too. I’m glad my old parts could help out and appreciate what you’ve done to make this an accessible option for those who are interested. This is truly the best online community ever!

I couldn't upload a video file so I posted it to my YouTube. You can see the part bending (and my poorly placed coolant hose). Obviously 3.2mm chromoly steel or stainless will not bend like that at all. I couldn't suss out the point of the bent tab so I left that out for the sake of cost while adding a lot more material. I'll have to make sure the choke cable is also out of the way. It looks like the choke cable is leaning on the bracket but it isn't, it's just already twisting from the pressure.
