so since i got the seat mounted and the steering column mocked up i was able to build my steering shaft and cut the firewall for the column. i didn't take any "in process" pictures just the done ones.
it just so happens that 2 1/2" exhaust pipe works very well for a pass though when you have angles to deal with.
inside of car
outside of car
shortened the steering column about 7"
then built a lower column mount since the firewall is no longer a mounting point.
then i got the intermediate steering shaft done. i had a few GM shafts laying around that were being scrapped at work. the rubber boot is from one of the cobalt steering shafts. so parts from the cobalt shaft and a impala shaft were made to work. its also collapsible to reduce vibration. so far it works pretty good, once i tighten everything up to double check we'll see if it works. if not then i'll build a new one with double D shaft and joints.
p.s. 2 turns lock to lock, pretty quick ratio steering gear.
