Looking good brother
Thanks man. When I did the 5” drop I got the vibration from the bad pinion angle, so I put in a tubular crossmember with different mount holes for the drop. That almost had it right. Then I got some of the angled shims because I figured I’d go another inch lower, and it would put everything about right.

You could flip the brackets on your crossmember to get real close for free, and an afternoon.

When I made the arms, I did it the redneck way lol. Traced it on the welding table, then put the shim on it and drew a new line. Sorry I don’t remember the exact angle. I threw those notes out when I sold that house.

It’s not really too hard to make the arms. I’d definitely recommend the heim joints so you can go back and forth an inch. I got those and the bungs off Barnes 4WD. Really quality American made stuff. The ones I got are rated at 38K lbs or something like that lol
