1947 GMC 622 SEMI The cab is 'SOLID' Steel, with only surface rust. A great KEEPER as is with WORN paint, but, great look. The motor is a 5.9 Cummins 'P-pump' diesel (highly rated motor). I bought it last year. I had it covered over to a NEWER more modern frame, with air brakes, etc, diesel motor, turbo and Allison Transmission. I wasnt going to turn this into a 'RAT' Rod. I love its originality. It was bought from a Farmer. Its a 'STEAL'. You will NEVER find a GMC 622 in this type of condition, with all over the more modern upgrades. The motor runs 'GREAT'..but isn't hooked up. The cab and all other hook ups are up to you, but, everything is their to finish. This is a BEAUTIFUL TRUCK. It also has practically BRAND NEW TIRES. Just the frame, motor and tranny with tires are 'WELL WORTH' $10,000 by themselves.*** The Allison Transmission is automatic.
