I have a good working 727 from a 1977 318 van including converter and flexplate. I found a 95 Dakota with a 318 and a bad tranny for a good price. Will it bolt up and work? Will the engine still run with the trans connectors unhooked. I know it will need a driveshaft modification and maybe a tranny mount adjustment. Possibly have to get a new shifter. I dont care if the speedo works. Anyone done this? Any input helps. Thanks guys!
