Clearance is very tight and took many hours to get fitted. The bracket was cut from a chunk of 1/2" angle iron.
Tried a half dozen pitmans to find one with the right length and angle.
I stayed with the Astro wheel. Went to floor shifter so ground off column shift pivot and bondo'd it smooth.
Length from firewall bracket to steering wheel is perfect without adjustment.
4th picture shows size comparison with original Saginaw box.
