<VV> LM - windshield & backligh sealer/adhesive

[Kinzelman, Andy]

Guys,
I am going to help another Corvair guy install a windshield and backlight into his LM coupe.  I have access to rectangular cross section sealer/adhesive strips.
Does anybody have a recommendation for the size to use?  My glass guy thinks he recalls we used a 5/16" for the windshield and backlight; but that the backlight may have fit better with a 1/4" thick strip.
Thanks,
Andy K.
