1990 Regular Cab, Stepside Cab Mount Dimensions

[swartmf]

Hello,

I'm currently restoring a 1990 Regular Cab, Stepside 4WD GMT400 pickup. The holes for the cab mount were rotted out so I had someone cut new cab mounts plates from a CNC plasma cutter. However, I have not been able to find any information on the dimensions for the cab mounts on the truck so I can make sure the mounts are placed accurately before welding them. Any help, especially drawings with dimensions would be greatly appreciated.

Wouldn't just bolting them up to the cab eliminate any questions of where they go? Then burn them in. Not trying to be a smartass, but sometimes the easy things are easily missed. But if you already have the cab off, makes sense why you are asking.
