Title: Size of original Battery tray mount and clamp bolts???
Post by: 1967RS/SS on February 23, 2013, 01:38:21 AM

Does anyone have the specs for these bolts?

I need sizes for the two rad support bolts, the two tray floor bolts, and the clamp bolt.  Thanks!

Not sure if I have this right, but I have four bolts lableled batt tray.

Two are 5/16 by about 1/2 inch long with large 1.125 inch captured washers.  I THINK those are for the bottom.
Two are 5/16 by about 3/4 inch long, pointed, with smaller 3/4 inch captured washers.  looks to be the same as the headlight bucket bolts.

Not sure about the clamp bolt.  I know it is 5/16 and know it has a captured washer, but not sure of the length.

 As a suggestion, if you have the Factory Assembly Manual and if you get a copy of the AMK products catalog, you can see what the fastener sizes should be right down to the bolt size, head marking (most of the time it's correct), thread pitch and finish.

Thanks, exactly what I needed

Thanks Mike. I looked at the AIM and got the p/n's but never thought about using AMK's catalog.  Have to remember that next time...

AMK doesn't have a bolt for that specific part #.  I believe it should look like this;

Actually, I think the hold down bolt has the washer as part of the hex head, not just captured as the above, which means I may have misspoken in my first post.  Could be wrong.

Pretty sure I have the other info correct.

An original hold down clamp and bolt to compare to repro's. This one is a RBW version & the captured washer was large.

Hmmm.... great pic.

Is that on your 68?
Thinking 69 has the one similar to the hbc pic.

Been wrong before.
