One wire lock-up, 4 spd automatic w overdrive into A-body.
I'm at the point now, where I have to get under the car and wire wheel the seem along the torsion bar crossmember; so I can weld it to the floor all the way across the width of the car to strengthen it some. There is a small gap right at the transmission tunnel that I will either close up with a few taps from a mallet or back fill with some thin strap steel.
Near the location where the stock floor shift rod passes through the floorboard, there is the largest gap. This is where Treblig did a lot of his custom work to retain the factory shifter. Mine is going in a box in the basement, although I am keeping the factory console. I am going to make some modifications to it like a gauge pod mount at the very front of it and put a drink holder in where the current ashtray lives.
