64 Dart GT Slant 6 Convert to 4 speed manual

Since you have a 64, the best donors are going to be 64-66 for the bellhousing, pedals, Z Bar, etc. the floor hump for those years is not reproduced, 66 is different from 64/65 where the shifter mounts and spendy when you can find one. Those years will use the 833 with the ball and trunnion flange which should not be consider a deal breaker for either the B & T driveshaft or preferably the conversion driveshaft. You can use the later 833OD which will require the OD bellhousing. It will also require some other conversion parts as a friend of mine found out for his 65 Valiant. He sourced them from Brewers. IDK if a 67-up 833 will bolt up to the 64-66 slant bell - Brewer’s would know for sure. Hope this helps some
