Is the round plastic upper window stop available as a reproduction?

Flatback72 · Nov 28, 2024

I changed my window anti-rattle guide today in my left door, also found one of the round plastic window stops had fallen to pieces. There's only about a 1/4 of it left so I've turned it around so the last 1/4 is functioning correctly as a stop but it ain't gonna last long.

There is a couple of NOS items on ebay but priced accordingly.

Does anybody know if this part is reproduced?

Check with Mike at Motor city mustang. He's a vendor and supporter of the forum and and all around great guy. He has them on Ebay. You might want to contact him.

A previous owner reproduced one of mine with a hole saw through a piece of plywood.

Maybe one of our tech savvy members could 3D print some? I suspect most of ours are junk.

I have a printer. But would not bother trying to print one up.

My wife has all sorts of polymer, clay, and epoxy with a vacuum chamber. This part looks like something you could clone by casting and molding it. The epoxy is a million percent more durable and UV persistent than the sort of plastics you can 3D print on a home printer.

I have several original ones in good condition if that may be of interest to you.

Thanks for the replies everyone, it seems these are not reproduced. I found a second hand one for sale from West Coast Classic Cougar for 11 bucks, so problem solved for the time being.

I don't think 3D printing these would provide a durable part. The original items seem to be made from plastic but I reckon machining pieces on a lathe from nylon bar stock would surely be a good hard wearing alternative (I'm a machinist by trade but now I'm retired I don't have access to a lathe anymore though....)

When the second hand stop arrives in the mail, before I install it I might measure it up and post the dimensions here in case it comes in handy for someone in the future who might like to turn some up out of nylon.

I just came across your post. I needed to replace the door glass on both doors for our 73 Mach 1. I removed the inner door panel and found the various parts attached to the glass was using rivets instead of bolts and nuts like in 1970 - 1972, and pre 1969. I figured I would end up breaking one or more of the parts, so I purchased used plastic parts for the glass retention and regulator stops from WCCC also. I hope your parts are secured by bolt and nut, as it is far easier to unbolt those parts as opposed to drilling out the rivets. because I was going to replace the glass anyway I ended up using an air impact chisel to shatter the glass, where I only had to vacuum up the glass pieces. I bet hat was faster than drilling out all thise rivets. But, if you need to keep your glass that is not recommended <g>.

If you are interested to see what I did with the door glass replacement, with the attachment of the lastic pieces, you can go to some YouTube links below:
