Thanks. I watched a guy do one on you tube. He just cut a piece of metal to fit, then welded it in. Not sure how easily whole top six inches or so will come out of a donor but I believe that will be a better and stronger method. Ride height could possibly change by the thickness of the metal but it beats what we have now.
Just went thru all the pages of your trans swap. Incredible amount of work you did. Wish I had your youth - and your Dad. As one of the posts mentioned, he has some serious skills. I didn't see it but was wondering if Redline ever got back with those Chrysler part #'s. Oh well, I'm sure I can find them. Thanks again.
