I have a 69 C/10 it has a 350 Small block with a th350 transmission. I change the rearend that was in it. Put a posi 373 in it. My problem is, I'm geared to low now. I would like to go with a 4 speed automatic transmission. one with O/D. Is that a 700R. I read in a thread I'd need to move the crossmember back, and no doubt would have to change the driveline. Anyone running this setup. Or have an idea on what I need. I like the low gear rearend, but still need to run the interstate from time to time. Thanks for any advice in advance
