Post DJM 4” block help

Noticed my driveshaft pushed almost an inch into the transmission and the u joint makes contact with the housing. Checked the install and pins from the block and saddle lines up perfectly but assuming the taper is whats causing the issue? Any body else had this issue? I see alot of people running blocks 4” and above with no issues. 3rd pic shows the scribe on stock height after removing and inspecting the axle and drive shaft which was also moved forward closer to the tank, last pic shows making contact.
