Bumper bolts, rear '64

[Jean C.]

Are typical production rear bumper bolts on a '64 of automotive grade quality? A set of bolts with an acceptable head mark ("M") that is hopefully/possibly/perhaps styled correctly that I received from LIC are regular bolts, cad/zinc plated.
Thanks and best regards.

Charlie, Right before the Seven Springs regional I spent about 6 weeks on the bumper project on my 63. Getting the correct hardware is no easy task.
The rear bumpers on your 64 most likely were held on with TR's and possibly WB's also. In fact a lot of WB's were used. The later midyears used M's and RSC's, etc. Before I get in trouble here yes I am aware of the fact that numerous suppliers were on the payroll.
But know original examples of 63 -64's used mostly what I said. Now we are talking rear bumpers. Front is about the same idea.
Charlie you need to get the correct bumper washers also. The originals are about 1/16" thick and are SAE. Readily available at industrial supply houses. I had a bunch of them but sold or gave them all out to friends. They are readily available. The repros are larger and extremely thick.Look for flat washer: .925-.926 and 1/16" thick. ID is for a 7/16 bolt. Look in the aims for usuage. Be careful as it is tricky.
The nuts are unique also. The repros are incorrect but not the suppliers fault as the real deal just are not readily available. The 7/16-14 hex nuts use a 5/8" wrench. I saw judges checking on this nut. If you buy a 7/16 nut today it is 11/16". Basically you need to start from scratch if you are going to have your car judged as far as the bumper hardware goes.
But as far as using the M's on a 64 I would call them service replacements. The originals don't appear to be anything other than grade two hardware. No grade marks. After you have accumulated all the correct hardware you would want to get it cadmium plated.

Charlie on the 7/16-14 nut problem I got some 7/16-14 coupling nuts( 5/8 wrench fits) and cut to proper length. Good Luck

Terry, I checked every industrial tool supply catalog I could think of trying to get those small OD nuts. Couldn't find them.
You know it wouldn't take much to have some of those nuts made using hex stock. Someone with a small lathe could easily pop those out.
There were some on ebay for sale. 20 nuts for only 50 buks. He had no takers. Sounds like a lot of money but you have no idea how much time I spent looking thru friends bolt and nut collection looking for those 5/8" nuts. Then my pal Barry gave me the balance I needed to finish the job on my 63.

Thanks for the info. My '64 is late production (17XXX). I'll ponder this and determine a course of action.
Best regards,

John I needed the 7/16 with the 5/8 flats for my '62 motor mount bolts and I too looked everywhere with no luck. Then I picked up a 7/16 coupling nut BINGO! I took my die grinder with a cutoff wheel and cut to length without losing the finish.Didn't take but a few minutes. We'll see how good a job I did in St. Charles.

Terry, I bet if you would have hollered here some of the guys would have sent you some. Good luck on the show. John D.

Hi John I don't know why I didn't ask for help on those nuts I've never seen anybody go away emptyhanded if what they needed was available. Thanks

I still think that some supplier out there may have the 5/8" nuts available. I just can't find out who.
