Thank's layedout.
I think it's harder to explain it than it is to do it but here I go.
You will have to measure your stock frame to get the with and the distance from the front to rear mount's, then to get the height what I did was to tack 2 square bars under the frame,these bars will support the weight of the cab so that the bottom of the cab can sit level with the bottom of the frame wich means that if you lay out your frame you will also be laying out your doors :twisted:.
After that was done I made a cardboard template of the mount and trnsferd it to a 1/4" plate, remember to take into consideration the thickness of the rubber mount plus I gave it 3/8 more to have some adjustment if I need it cause it's essayer to shim the mount than it is to cut a weld it again.
Hope this makes cense
