I noticed that a couple of those RDs seem to have their jockey wheel cages clocked back too far, as if you do not have the cage stop screws installed on the outer cages, near the lower pivot. The stop screw is part #15 on the exploded view of the RD posted on this thread......
It will make it much easier to install the RDs with those stop screws installed, as you will not be fighting the lower pivot springs too much.
