Re: 72 GMC Longbed Duramax Swap

Subscribed and good luck with your build. I used the same mount adapters that you have posted. I went from the adapters to a small block prothane mount to factory small block engine stands on the frame. I had to space the stands up 1.5" on the frame rail and 1" on the crossmember for pan clearance. I guess you know you have to raise the trans tunnel to get the Allison to fit. The forklift will sure make it a easier. I think dmax/allison is around 1100 lbs and is a little sketchy with a cherry picker.
