914 glass butyl, I searched and got confused... Options

[Kansas 914]

I am replacing the front and rear glass in the flared car when it gets back from paint.

I have read where the front windshield should use 3/8" butyl, but then there are warnings that this is a tad thick and if you don't have a warm day to press the glass into the butyl the trim won't click in.

I think 5/16" inch is a better solution. Does anyone have a source for 5/16" butyl? Does it really matter whether the rear glass is 3/8" or 5/16" since there is no trim just interior pieces?

Thanks in advance!

McMark,

for the rear glass, I believed 3/8 is the original size but I read from few thread here that it is better to use 5/8? I did mine before with 3/8, but after few months I got water leak again.

Hi Noel,

I think 3/8" (10mm?) was original from what I have read in the workshop manual.

Anxious to see Mark's response. I think the glass might get close to trim piece with 5/8"?
