Name that part

Nope. I have these on the firewall of my Spyder, they are mounts for the top. The main bow slips down over these. They are mounted high and wide on the firewall. I'll take a pic and post it when I get a chance.

Well, maybe they are for CMC side curtains, but they are also for the top to mount to on my Vintage Spyder.

Wow....Dual function CMC parts.

Who knew?

BTW:  A couple of us have taken the lead of Ola Miltorp over in northern Europe (Norway? - Can't remember) and fabricated these permanent replacements for those after the CMC parts rust out or get pitted.  They are, after all, living out in the rain, no?

The replacements look like this and have worked great for over ten years now:

Slammed23window touched on an issue I was going to ask the SOC community in the future and now is an appropriate time.  After gathering up my CMC family heirloom in Orlando I put the side curtains aside.  Obvious they need to be replaced.  My brother confessed these weren’t on his priority list in the early 1990s so stored them storage in a safe place was not taken into consideration.  Both curtains’ have that “frosted” texture and weather strip at bottom is missing.  One curtain is broken.  Is it feasible to reproduce these with a heat gun to match the for or profile in the top forward section of the curtain and where I can find weather stripping for the bottom or where do I find replacement curtains?           

Dennis, you may be best off buying new from like VS, unless you can find a set on Craigslist or Ebay. If you had all the rubber it is fairly easy to replace the plastic. I replaced the plastic on mine as one side was broken, the other had a crack in it and both were really 'frosty' and scratched up. I bought some clear Lexan in the correct thickness at Home Depot, made a pattern out of light cardboard(the original CMC's did not quite fit correctly to the windshield frame or the door) then cutout the pattern, traced it onto the Lexan and cut it out using a sabre saw with a very fine tooth plastic/fibreglas blade. Used black silicone on the rubber, letting it set up some then fitted the windows in.

Since the side curtain posts were rusted and pitted to bad to polish out I sanded the pits out and the chrome off with a Dremel tool, primed them with several coats of primer, ending with a final coat of hi-build primer then painted them with 3 coats of black epoxy and replaced all the nuts/bolts with new SS ones.

I used the original plastic to locate the holes for the posts, put tape on the location on both sides of the lexan and marked the holes. DO NOT try to drill the lexan with out first reversing the drill bit to score the surface first, otherwise I can guarantee you will probably crack the lexan...been there, done that replacing lexan on a boat in the past...

Gary's info is right on.

McMaster-Carr might have the bottom/front weatherstripping you're looking for.  The CMC side windows do not have the fabric border all around them as the VS windows do, so they offer a little more visibility (always a good thing when you're riding in what seems like a gun bunker).

Most of the clear acrylics you'll find at "Home Depot" are .096" thick.  If you want 1/8" (.125") try a local glass shop or a boat top place.  Mine are currently .125" and I've often said that if I replace them I'll go thicker, like 1/4" like Bill Drayer on "Blackie" just to keep things from flexing at highway speeds.

That said, my car has over 16,000 miles at 70+ mph on freeways and I've never had a problem with the side windows popping out - that depends on the fit to the top, too, though.

Try reading the article on "Installing a convertible top" in the Knowledge Section of this site for a little more info on side window fabrication 

Thanks Gary and Gordon for your input.  I work at Home Depot and every time I pass the lexan/Plexiglas bay I think one day I’ll present the CMC side curtain question to SOC.  I have experience cutting Plexiglas but no experience molding or forming.  As suggested I’ll look on ebay and or try my hand at making a curtain.  Prior to re-installing the top on the speedster I read Gordon’s installing a convertible top doctorial thesis.  This is very informative document.  I appreciate the referenced to use Weldwood contact cement (green) as an alternate to Pliobond.  That was a big cost savings.  More superfluous information; when my brother got his CMC on the road one his babes wanted to take a ride.  She sat on the top in the back.  Later he attempted to raise the top and the bow was a wet noodle.   Like the side curtains he put that in the pile of projects to be done.  I repaired the bow and requested assistance of Tom –aka- Pepspeed.  Thanks to Tom the project is complete.  Some of you might recall last week Tom was an unwilling participant of Speedster open fuel ignition testing.  This was a destructive test and his Speedster is waiting transfer to the bone yard. 

Again thanks your help.
