We are thinking about swapping the Jetaway transmission in a friends 69 Cutlass with 350 engine to a either a TH 350 or 4 speed manual. Are the 350 cranks pre drilled for pilot shaft bushing? Can the same flex plate, rear mount and drive shaft be used if we go the TH 350 route? Will the same drive shaft work with the manual trans? Thanks!

 

Not unless it came from the factory with a manual trans.

Yes and yes. You'll need to get the correct A-body accelerator pedal that has the provision for the kickdown cable. The firewall on a 69 will have the square hole for the TH350 cable already punched and a plug installed with a screw, making this pretty easy.

 

Sounds good, thanks
