VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1929-1932 32 Closed car windshield trim install question

I got my cowl rubber and trim installed, Ive got the rubber in the big 'horse shoe' piece (that goes up the A pillar and across the top and back down the A pillar) But no idea what fastners hold that in place. Or what the fastners would be called to look for some.
Been piecing the car togehter for years, just hard to look for fastners not knowing what i'm looking or. any help would be appreciated as usual

Thanks,
Jeff

My manual says for removal of the reveal molding to remove all drive screws in the upper weatherstrip retainer and all tacks and nails in the pillars. The horseshoe upper molding and the lower are joined at the corners by a metal angle piece.

Guess the question is what size are the drive screws? And any info the nails and tacks?

I could not find a listing for the size of the screws but did find the pt.# 4078528. Perhaps someone has a listing. The hole size in the molding should help to determine the nail/screw gauge .
