Sorry, can't help you, but you reminded me of my first truck, a 71 lwb custom 10 with a 307 and 3 on the tree. Which I later converted to 3 on the floor via a hurst shifter. Well to make a long story short, one night my Dad had to tow me home after I broke the driveshaft in THREE places while shifting into second. The ole 307 was strong.......that was 21 years ago, and I'm still messing with these 67-72's.
