Hi Rob

I think by now all most all CMP hinges are bent from a little to unusable. On my two Pattern 13s I resorted to making wedge shape shims that fit between the door post and the hinge. Using these I was able to get the doors into proper alignment.

Picture below is of the drivers side top hinge on my HUP shims have been in since 1978 when you look close they are not as pretty as they could be. When I reassemble the HUP plan to make new ones that will follow the shape of the hinge lip.

I'll take a picture of the shims alone and post it.

The next step would be to make new hinges which I think can be done. On my Pattern 12 the hinges were so shot that making them was the only way to have doors that opened. Whats on the 12 Cab now work well but need to work on making them look more original.

Cheers Phil

Hi Phil,

As usual, you come up with such elegant and workable solutions! I'll try the shim solution this coming weekend. Bob had mentioned the possibility of shimming up the hinges, but I was fixated on how to shimmy the door side hinge, and couldn't see how it could be done. Just another example of not seeing the forest for the trees.

Hi Phil & Rob,

Any thoughts on worn hinge pins being (at least) part of the sloppy fit problem?

Good point Brian, and there is a simple easy solution, Chevy didn't change its pins or the T head bushing I've found them at the local auto parts store. If some body knows the year cross over that would help. But I just took an old pin and one of the bushings and had no problems.

I'll have to check all the hinges on my HUP to see if after 30 years they need to be replaced again, if they do I'll post the parts number once I find it.


Cheers Phil

Brian and Phil, Yes, the pins have some wear on them, but that wear is not the problem. When the hinges are bolted to the door and the truck frame, the door does not have the proper clearance at the hinge end to close. I am not sure that I am communicating the problem clearly, so I will take photos next trip to the barn.

I have a good stash of pins thanks to a previous purchase, but do lack the bushings. Phil, I am looking forward to your posting of the bushing part number and the parts source(s)?

Thanks, R

Let me jump in this .......

Oddly enough the front hinges are in very good shape and the pins not loose.

The problem was created when the doors were reskinned and the alignment problem is where the hinge section fits inside the door panel itself......seems the pitch of the sheet metal was altered and pushed in or out.

If we try.... and we will.... to fit wedges of some sort they would have to be on the inge section that fits inside the door and the bolts are inserted from the outside..... the small cut out that allows the hinge to fit inside the door limits the thickness of the wedge that can be fitted.... or maybe we need to instal some wedges on both end of the hinge to split the thickness...

Pictures will make it easier to understand....

...and the weather is finally warming up for the weekend..... +7 or 8 C
