'68 cuda window trim help

Just a thought... message this member and ask him to look for a different size clip anywhere.
[FOR SALE] - Parting out 1968 Barracuda Fastback
I found the taller GM type clips to be too tall anywhere I placed them on my notchback, except for the lower front where there isn't a fence. Those were the only clips I could find back then (before the internet). I took them and a vise grip to the grinder and and took about 3/32 off bottom of all of them.
I dont know that a vinyl top car had taller clips where the vinyl was but its possible. If thats the case, aftermarket is providing a "one size fits all" package.
