No Problem man, I'll pick up the hardware tomorrow and ship it. I already bolted it onto a worn out diff and spare a-arm on the bench and it all fits fine so you should be good to go. Just use your original bolts to bolt it to the diff and the new grade 8 bolts, nuts, flat washer and lock washers to connect it to the A-arm.
I really would like you to abuse it to see how it holds up, I can always use 3/8" plate and a heavier wall tubing if there are any problems, but I don't think there will be. I contemplated putting a few gussets in on yours since it was 3" but that makes it more difficult for wrenching later on, lets just see how it performs like this.
Regards
Jim
