My friend tried to switch just 88 arms into his 84 and found the spring plates and a bunch of other stuff was wrong. Parts should be cheap enough that you could easily buy the whole assembly. People parting out cars probably only get $200 for the entire rear suspension because nobody ever buys it piecemeal. For that reason I'd buy the full meal deal no matter what year/offset you decide on. The mounting points to the body are all the same.
The 87 and later stuff is nice because you can use all the late offset wheels- C2, 993, 996 etc. but you'll have to use spacers up front because that axle will still be narrow. If you have 31mm torsion bars I think you can still use early offset wheels and they'll completely fill the fender and not rub.

So let me make sure I read you correctly;
*If I get '85.5 or '86 aluminum arms, I won't need anything different, just swap and go? Same CV Axle length and can use the same brakes?
*If I get '87 and up I have to change out a mass of things including CV axle, Torsion tube (so the mount points where the arms pivot are wider than mine? or would I be ok with my tube?), and whatever else I may need? (I'm actually hoping to avoid changing out that bar/tube since I don't have proper tools as of yet to drop out such a heavy thing, let alone install one)
But I too am on the hunt for these babies for several reasons but the main being that I'd feel allot more at ease with those bigger bearings and with just one per wheel rather than two per wheel and so skinny. Mine I DO NOT trust as every time I make a turn above 20mph, there's a constant 'ching-ching-ching-ching-ching' noise and it's rather a -large- sound which is making me think my rotor is kissing my calipers, hard to pin point if it's the front or rear though. Frankly, I'm scared *****less they will fail again as they did before.
I just feel the aluminum arms were a MAJOR improvement for these fine cars and allot of people tend to overlook suspension components it seems
Also, what spacers would I need if I go with '87+ arms? I do not have late offset wheels yet, still have the Cookie cutters
