Mines a Dana 60. I had a cracked crossmember when I bought the truck so that was swapped out for an ORD unit early on. I'm also running my 52"s from out back in the front and have the axle moved an inch forward (all the way on the b52s).
I dropped a 2wd sector shaft in and am running the ford van arm from mid 70s to very early 80s e series. I've been pulling them when I find them for spares/other people and have seen a couple on the early 80s vans with square headlights.
I'm running ballistics springless hi steer arms but decided not to run hi steer due to knuckle concerns with the assist (surplus center ram and kert's cap) in the rocks. There were some clearance concerns there too...not that it wouldn't fit but just that it was crowded enough as it is. The pitman arm clears everything by around 4 inches but routing hydro lines and working under there was going to frustrate me.
I went ahead and reamed my pitman for a gm DLE. Didn't pay much attention to what it was tapered for, but I posted the measurements at some point in the for sale forum.
My steering arms are too long and I lost some turning radius. Not enough to really bother me, but I'll probably make some shorter copies of this design eventually. Running a longer pitman would not be a good choice because the drag link already slightly angles back and I'd like to go forward more at some point. The ballistic arms are really long and the tie rod hole is actually exactly the right length for my drag link, but I don't want to ream that or they won't be any good to sell used in the future for someone elses hi steer.
I made my drag link from 1.5" x .250" DOM with welded inserts and my tie rod is threaded 1.5" x .375" DOM. I run ES2234r on both sides of my tie rod and ES2026r on both sides of my drag link. I've had trouble locally with DLEs and TREs being stocked well (I always find them, but not always at the first store I try). With all rh thread, I just have spares that fit anywhere when I break something on a Saturday night. I noticed the dodge ES2010 l/r TREs are always special order around here and they're the same strength as ES2234r anyway. es2233l is the long weak one with the stabilizer hole.
