The bolt head is chrome plated the washer is steel.
We may be talking 2 different parts here. The bolt I'm talking about goes in the top of the convertible frame and attaches the top bow to the convertible frame.
What I see on page 7-15 is hood and cowl details.
I stand corrected, there are top bolts in the 1933 Cabriolet convertible top.
I'll post a picture (f I can figure that out) and there is a washer between the bow and the frame.
Shoulder bolt:
Hex head 5/8 x .160 thick
Shoulder 3/8 diameter x .450 long
Thread is 1/4 28 x .290 long
.900 Overall...
Looking for the shoulder bolts and nuts that attach the nickel plated bar that connects the convertible top to the door pillar.
The bolt is at the door pillar and attaches the bar to an elongated slot.
I believe the part numbers are:
Bolt: 40-764864
Nut: 40-764862
If you know where I can...
