How to mate A833 to 72 /6 in 1962??

As mentioned, you need to match the transmission to a bellhousing. If you have the direct drive Autolite starter, I'm not sure if you can use it with the later bellhousing. You may have to change to the Chrysler starter type flywheel but check with someone who has done that swap to be sure. The Z bar linkage will have to be modified to fit the later aluminum bell housing. You'll have to make a custom bracket for the bellhousing end. You'll have to get a different driveshaft with the proper yoke (which is a good thing in your case!) and you'll have to cut a hole in the floor for the shifter. You'll also need a '66-7 speedometer cable, and the later gear, and holder for that transmission. I can't think of anything else but I'm sure someone will!
