Don't listen to all the naysayers about how weak the D35 is. I ran one in my '88 YJ (non c-clip) with a built 350 and 33" Buckshot mudders, never had a problem. I know run my '95 D35 hard behind the 2.5L with 33" swampers and a welded differential, no problems. I say run it until (if) it breaks, then upgrade.
