I also missed this awesome GTO thread the first time around, what a fantastic time warp in one of my favorite color combos!!
The M30 trans is also know as a ST (Super Turbine) 300. I rebuilt a couple of them during my tenure as a dealership trans tech a LOONG time ago. I always felt that it was a superior 2 speed trans compared to the Powerglide, like a TH400 minus second gear.
Thanks for sharing!!
