The chevy version is not the same as the dodge. Input and output shafts are different. This is to go behind a dodge smallblock. I do have a nv3500 5 speed but it has no speedo sensor so would need a gps speedo. I sold my nv3500 with speedo couple years ago.
I would like a whole setup because the OD trans has its own bellhousing. There is a 318 with 833 on kijiji but its priced to high and a bit of a drive. I'm in no hurry so I can wait till something comes up.
The 5 speed would be the better choise. spend 200 to 400 on a gps speedo and you dont have to think about tire size correction miles/ km . plug and play .
