RE: [VACList] '63 FC window glazing replacement

[RJ.Dial@xxxxxxx]

Does your seal look like the profiles on this page?

This style should fit the 1962 (& some 1961) to 1965 windows.

Another idea is to check the window thickness.  It should be 
single-strength glass (3/32").  If someone has replaced it with 1/8" or 
5/32" glass, the retainer is very hard to fit.  

Another tip is to soften the seal in hot water first - and be sure not 
to stretch the seal too tight when installing - try to get as much seal 
length as possible into the opening.  That way, as it shrinks with age 
it wont pull out and leak.
Best of luck,
RJ
