I'm with you Rockie. There are probably different manufacturers but why would anyone use something other than mild steel? These are raltively crude, handmade items. Probably hand formed over a mandrel and welded in a jig.

Also from an engineering standpoint I would want something that would deform rather than be so strong as to transmit that energy elsewhere and break something else...

The problem I found is that the mild steel distorts when it hits an obstacle and drives inself into the sump. I guess it is preferable to have the steel guard hit the sump rather than asphalt or concrete, but now you have the distorted guard up against the sump fins, rattling and buzzing until you drop it down and pound it back into shape. Then you get the fine experience of having to reinstall it and wait for it to happen again!

I took mine off....

Yep, the originals were all made from unobtanium iron ore from the famous iron mines of Tuscany. They were specially hand crafted in the Autodelta performance shop to have the perfect blend of shock absorption and sump protection. Few of the originals remain, and few of the old world craftsmen who made them remain as well. The ones available now are made of mild steel.

I'd recommend taking a quick look at this page. No connection at all with the company involved, etc.

Hi,
Care to get rid of that guard. I need a good wheel chock.

on the front bolts try this, get 2 bolts about 10 mm longer than the old one, run a nut onto these new bolts,, then grind a taper onto the extra 10 mm of bolt you just bought, then they well slip easy into the bolt holes in the sway bar mount, just wiggle the untreaded tapered part into the holes , then tighten.

I need to see photos of this.
My bolts are sheard off and I cant figure out how to replace them.
They seem to be coming through the box channel and there is no access point. Do I weld them?
Can anybody provide photos or a procedure for replacing the bolts mounted through the swaybar bushing support??

Get out there and DRIVE !

Well that may work fine, but on my car at least the original threads have taken a beating from such ham fisted manouvers, so when I did mine, in an effort to preserve the original threads, I used new bolts and used a crow bar to tweak the sump guard into position so I wouldnt have to to anything which might put further wear and tear on the original threads in the cross member. And always use anti seize compound of course.

I'm still looking to do my part to help some indecisive owner of a new still in the box sump guard. If you are one of the aforementioned. I will pay reasonable freight and compensation or pick it up if in N. Cal and take it off your hand's for Christmas.

Have had one on for 33 years that the dealer gave to me when I bought the car (requested). I had to drill the rear holes and installed longer bolts in front. I used aircraft nuts on the rear. Pros - It has saved me from several bone shattering hits on road stuff, twice needing guard bodywork, and once some re-welding. It also helps protect from all the cumulative little dings from speed bumps and parking stops since the pan sits out in front of the wheel line (putting the guard out even further now by 1" or so, a warning device of sorts). If I hit the legendary John Duncan Yule log (or similar item), I figure it may act as a skidpan and help me ride up over it a bit and not chomp onto it. Cons - Cost/maintenance. On a small near miss, where you might have missed or just skimmed the pan, you will now hit the guard. It adds up to 1" of depth or so. I just can't see the 1/4" of incremental metal straps between the road and pan causing the engine to push up in a really hard impact. That impact was so bad it would have happened anyway. Methinks an Alfa urban legend there.

I have seen a model with small vertical reinforcing ribs welded onto the outside front half of the longitudinal metal ribs. That reduces clearance even more. If you drive back roads, I'd say it's a must. It also seems like there is just more flotsam on the freeways these days too. My 2 cents.

IAP is out of stock on the Sump Guard and has been for some time. I checked yesterday. I am not sure about Centerline. I have never seen one of their's and am reluctant to order sight unseen.
Thanks for the suggestion .

Well I think Alfaholics has them, though it requires you to make an international phone call, they ship quickly shipments arrive just as fast as a USA source. I have one of theirs on my car.

just tap a little bigger thread into the front.. also when you mount it, do the front's first.. but do not tighten ,leave a little room, then mount the rear of the gaurd, then tighten all the bolts.
