Frets I can measure when I get home. I think that the front of the brackets were 18.5 inches from the front of the frame. I took pictures but havn't posted them to the internet yet. I should be able to use the driveshaft as I have moved the motor forward a couple of inches from where it was before. It eyeballs up real close. I was only changing from 3 speed to automatic and from front motor mounts on a bent piece of flat metal to a chevy duty unit. It's all in. Now to finish up putting the rest of the motor together.
