Thanks, I had two of these trucks and they had 4 cylinder industrial engines originally. I sold the other truck and axles along with the buick engine from the one I kept. I kept the brownie because I thought Id put it in again but got a fuller road ranger with air shift and overdrive mod. Also realized that a 702 V12 would toast the auxilary in no time with 600ft lbs of torque. I am trying to find out what this is so I can ultimately sell it.
