I have one in a 51 Chevy PU, great.Beware there are two models, the more common one has a funky Mopar bolt pattern, uses a factory modified clutch housing. The other model is typical Chevy bolt pattern,takes a 1-1/8 10 spline Chevy clutch disc and the out put spline is the Saginaw style. Like all Chevy car manual trannies, it's 21 inches long.The front bearing retainer is slightly larger than the car trannies or some trucks. I truned down the retainer to fit the 51 pu clutch housing which has the same sized hole as Chevy cars.
