Custom frame rear body mounts

[1970stub]

So my frame is custom and I just noticed that the rear body mounts aren't the same hieght. I'm leaning toward I need to fix them. Does anyone know how high the factory ones sit above the frame? Here is what I'm dealing with

[1970stub]

Which one do I fix? The high one or the low one?

I may have the factory ones if you want to put them back on as far as the height I don't have a clue they are already cut off.

Can you add spacers to the low side to make it match

I'm already going to do ORD's 1" lift block to fix a completely different issue with the core support mounts. I'll search posts and try to find a picture of some rear mounts. Cutting one off and repositioning it isn't a big deal

Did you check the frame for square? They could be off because the frame is tweaked/twisted? If the frame is off, you're going to have a really hard time lining up all the body panels...

The frame is pretty square from looking at it but ill run a level and plumbob on it just in case. Looking through other posts last night it looks like they sit more than an inch above the frame. I might put a 1/2 spacer on the low one to compensate. I already have enough welding to do with boxing it
