Great job and looking Sub !
Your handiwork is first rate
Some of them of that era had two piece drive shafts. With the center bearing mounted on a cross piece that had a hole in it
IIRC, if the rear end drops a bit too much at speed...that center structure & it's hole would cut a one piece replacement shaft in half...
Super cool rig and what fun with a 'built' 350. Guessing it weighs in around 3,500-4,000 lbs. Power to weight ratio close to muscle car range
