1965 Dart Seat Track - drilling new holes & do these tracks have height adjusters?

I tried flipping the brackets around... between the height adjusters and the length differences... it was a total bust. Nothing you can do there.

The brackets are two piece brackets.... Bingo... on the side without the lever, I'm going to put a 2in spacer between the two brackets, on the the otherside I can't put a 2" spacer so I'll redrill two holes too inches closer and move the whole bracket inboard.

After taking measurements I need to bring the front of the brackets inwards 4 3/8" and the rear brackets by 4 1/4. I'll get some tubing and washers tomorrow to make my spacers and I'm going to drill away tonight. I've double checked the outermost bracket really does not have any reinforcing, so its probably not needed. I'll use the factor seat nuts there.

And since I'm using the procar seat's sliders I'll immobilize the dart's seat adjusters.
