1970 Swinger 340 Hemi Orange 4 speed

Interesting pics of the pinion snubber area and the back seat supports. The 70 40-speed swinger I have had what looked like scars from a rear u-joint failure and also had the back seat support broken off the floor. The whole horseshoe bracket needed to be re welded down. These A body 4 speeds must be susceptible to this failure.
