Oh man...westcoast, you and I had this disagreement before.
You asked for proof and I said "I had them bolted on my car" and "I personally know others that use the da arms on their eg's" ...or at least something to that extent.

Want to know the difference? The DA bushings are 10.5" circumference instead of 10" - Ive measured.
How do you fix that? When you get new bushings, get the ones for a 92+ civic and use the DA outter bushing as an adapter ring to fit them (instead of shelling out the $100 for the mugen adapter).

If for any reason you dont beleive me, or for some magical reason they dont fit, you can always just swap the rear hubs (disc for drums) and presto...rear discs.

(Theres a reason h-t calls me a brake guru )
