I lost my hardware...

[Steven R]

So I am looking to replace some lost hardware bolts. I have misplaced the motor mount bolts the ones that hold the motor to the perch on the frame. When I try to find them online all I fine is the newer long bolt and tube style.

I remember the bolt was a 3/8 thread about 1.75 inch long and had a really thick washer on them. I just dont know where to find what I am looking for.

for the record I have a 71 gmc longhorn with a factory 350 SBC


now for the second set of lost hardware. I need to know what type and size of the three bolt and nuts needed to mount the torque converter to the flywheel. The parts store said to try the dealer ship... I really hate the thought of that. From my photos they look like a short bolt with a flange type head looks like a 1/2 inch head about 9/16 long. I am assuming they are a hardened bolt and nut. pls help

same truck 71 gmc longhorn sbc 350 and a 350 trans auto
