Trans mount

[Carmelo P.]

Can someone post a picture of
original transmission rubber mount bolts and washers?
Size is 7/16-14 with thick washers I'd like to know headmarks and if flat or indented heads...
Thanks.. 1967 Muncie

Carmelo,
Are these the bolts and washers you're asking about? If so, Rich Pasqualone has them for sale on his website.

Re: Trans mount

Leif,

Based on my research, the large, thick flat washers in the photo you posted should be unplated, and probably dark in appearance. They look to be zinc or cad plated in that photo.

I believe the flat washers should have a similar hue to the bolts and lock washers (GM 103328) in that photo. Those lock washers were dark (not very different from black phosphate) from their heat treatment. The same hi-collar lock washers were used at most bumper attachment locations from 1965-1967. The repro vendors typically have zinc plated fasteners in their kits.

Re: Trans mount

Leif, yes that's the bolt and washer. Would your pictured bolt SBC be an original?

Re: Trans mount

Carmelo,

SBC is one of several original headmarks.

Carmelo,
According to Rich, they are and I have no reason whatsoever to doubt his word.
