Patching rubber on stainless steel bumpers

Just retrofitted stainless steel bumpers on my 1980 Spider however the bumpers I used were missing the big rubber over riders. This leaves me with 2 large holes.

Any suggestions on how to patch these? Would prefer not reinstall over riders (even if I could find them). My original thought was to use black silicone caulking but colour would likely be off.

Thanks for your help.

I seem to remember that you could buy new rubber for those bumpers.

Thanks! Just did a quick search with the usual suspects but couldn't find anything. Will do a more extensive search when I get home.

looking thru most of the german suppliers, I'm not so sure you can buy new rubber inserts...

an older thread on the bumpers here (Lokki got his from APE)
http://www.alfabb.com/bb/forums/spid...oded-view.html

anyway I personally wouldn't just fill with silicone, it'll make all your hard work retrofitting these, look 'orrible

fit small lights there maybe until you find the correct inserts?

Might try to Photoshop some lights in there to give me an idea. Also toying with the idea of sculpting low profile inserts from hockey pucks (I live in Canada...). At worst it looks really bad and I just pop it back out.

Well, shoot. They were available at one time, but that was a long time ago.

I have a '74 and would like to remove the over riders as well. This seems like a good opportunity for someone with a 3D printer to create a plug.

My thought is to not try to perfectly match the contour of the rubber cover with the plug but to make it look like a mini version of the original over rider, just a couple of rounded bumps.

Now all I need is a 3D printer, a CAD program and a whole lot of trial and error...

Try Del Priore. They may be able to get them (Looks like currently out of stock). I bought a new rubber strip for the rear bumper when I removed the over-riders from a 74 Spider bumper. Not inexpensive...

Yes, that's what I would like to achieve. Just a smaller version of the big overriders.

Didn't know about Del Priore. Thanks for the tip. They do seem to have it but at 150 Euros, I'm going to start chipping away at old hockey pucks.... lol

But I'm sure they will come in handy when I start restoring my 65 Giulia.

I very much doubt delP has them....
...when it states "Auf Anfrage" it just means please ask (followed by...nope)
even when it says in stock you have to ask, because they rarely update their site.
