The stock rear end is still in the truck, it has . 4.11 ratio I believe. I want to bolt in the 3.23 rear I have. I will have to go to an open drive shaft to do this [which is what I want to do]. I was asking if the m/20 would fit the bellhousing and pilot bearing and such, those trannys were used in 60s and 70s muscle cars, they have a final drive ratio of 1.1 thanks
