No biggie Ron,
One piece angle, one piece flat cut to shape...drill a couple holes...weld togeher...
I still have the old ones from the race car buried in my mom's shed somewhere but they're for a 1 1/2" setback; I tossed them when going to motor plates back in the early 80's...
Don't forget to put in a solid trans mount too...and re-check the engine CL angle in relation to your pinion angle if lowering the engine...
If you're from the same Feddema family I think you are, this is all old hat to you..*G*
Have fun...
Pat
