Hinge bolt length

[FL71C10]

I am putting my doors back on my truck (finally!) and I am finding that I have two different size hinge bolts. I have a few shorter ones, and bunch of the longer ones. The only clearance issue I can see would be the upper door bolts could possibly hit the window mechanism. Then I have several with the pointy tip, as seen i the last picture. Is that for something else?

Thanks in advance for the help.

There should be plenty of room to use the longer bolts. They will be nowhere near the window mechanism.

Pointed bolts are 67
Shorter bolts are suburban 3rd door
Longer bolts fit the remainder yet all will fit without issues.

That's weird, I've never had a 67 or a Suburban. But these trucks had a lot of parts from other trucks on them so maybe somebody just had a box of bolts

Thank you both for the feedback. One more question: what size are the bolts for the hood hinges?

The original door bolts off my 1971 are (GR 5) recessed hex bolts with spin washers. The bolt threads are 3/8-24 x 1.1/8". They're stamped double F.

You can buy black oxide replacement bolts off Ebay, and they're expensive. They claim they have the correct markings, but no, they just have three slashes for grade 5. They're shorter than original, maybe 1" long, but should work.

The hood hinge bolts off the same truck are (GR 5) recessed hex, tapered end bolts with spin washers. The bolt threads are 3/8-16 x 7/8. They're stamped "ELH" or "E".

Thanks, Tony!

well, I found two Hood hinge bolts in my stash and I cleaned them up though now we just need to find six more!

You can get a front end bolt kit that includes hood hinge bolts, all black oxide. I picked one up for $35 off Classic Parts.

Regarding the original question, some of the hinges are stepped, some are not. In other words, some are thicker than others. I'm assuming the thicker ones used slightly longer bolts. I don't know why or what years.

I stated the differences in bolt length, its not due to he difference in those hinges.

I have the "thick hinge". The OEM replacements I bought work alright, but there's not enough thread for shims. In other words, they're the wrong bolts. My original bolts (not-tapered (Randy)) are 1.1/8" under the spin washer. The replacements are 7/8ish, they might declare an inch.
