I recomend that you will get your crankshaft machined for the newer trans. 67-> has the biggger hump on the converter. I have a lock-up trans from 89 behind my 273 and its good.:D
I want to replace the original 904 trans with a newer non cable version and use a B&M or Hurst shifter. The drive shaft has been converted to a slip yoke. Which years would work?
Thanks
