At the base price, the Spohn arms have mild steel adjusters. Add $40 for chromoly and they get more expensive than the UMI, which comes with chromoly standard.
He probably doesn't need chromoly adjusters but just trying to compare apples to apples. I don't see the gusset at the diff end on the Spohn either. The UMI appear to be for serious abuse...

I got mine from AutoFab. I liked AutoFab design better then UMI for my Chevelle. They are a little Beefier. Price is the same.
I have a Spohn ARB which is very nice. Wait for it to go on sale and save some bucks.

Those AutoFab arms have rod-ends rather than a roto-joint.
Good racing parts, but less street-friendly...

Just got back in town.
I went with the Spohn adjustable uppers part # 626, I’m sure there are better, cheaper, and more expensive but these will work. I need to adjust pinion angle more and I’ve run out of crossmember adjustment clearance, these will allow me to play with it..
Looking for a pair/set of adjustable upper control arms 64, 65 vintage.
PM me if you have something, I'll buy or trade.
Aftermarket.
Are you talking tubular uppers or truely adjustable as for racing ??
I don't have any, but here's my recommendation.

I'm lost. I thought he wanted front upper arms...
Makes more sense than adjusting caster/camber on the fly...
