I have searched and found lots of info, but was wondering. Would a drive line from a 1955 2nd series and up be a fairly easy swap for my 1954? Everything I have read about seems pretty involved. I have access to a 2003 Blazer S-10 4x4 that I have been thinking of swapping it's drive line into mine as from what I have read this is the rear to use. Would the 4.3 L fit in with a 350 engine mount?
