I noticed upon changing my body mounts that the frame has rotted the hole larger. I am looking the fix this. How big are the body mount holes on the frame originally? I can't find this spec anywhere. All I have to work with are the energy suspension bushings I ordered earlier (which I suspect aren't OEM size)

Energy suspension bushing dimensions (part that slides into frame). They all have play when put in.
rear mounts 37.0mm = 1.45"
front 46.2mm = 1.82"

The radiator support holes (almost immaculate) measure 50mm at round portion of hole and 47.5mm at flat portion of hole. I guess the irregular shape is to allow side-side play.

So that being said it's likely that the rear body mount bracket holes are originally something like 1 1/2"
And the front ones are 1 7/8" - 1 15/16". Assuming the rad support holes are roughly the same size as the first set of cab mounts.


Thanks!
