I plan on swapping in a v8 over the I6 for my 72' Ventura. Here's the problem, I want to use the TH400 transmission but I don't know which size tailshaft would fit the driveshaft of the ventura. For all of you who have done v8 conversions to a 71-72 x-body, help me out please.
Here's a list of what they in terms of tailshaft size
