the rear end in my car is a 74 8.25 and i bolted a carrier out of a90s dakota (with just new carrier bearings) but maybe its different than yours cause it a 74
You did not have to change pinion or gears, I need to learn more about this.. and your 74 is just like my 73, I looked at your thread not long ago.. Thank you for all your help and time here !!
