Yea, cheers for the update. Good to see a Rallye getting a thorough clean-up. I'm also planning to clean up the underside of mine but keep putting it off as I'm a) worried what I'll find & b) know it'll be an awkward, filthy, and long job!
I've been cleaning up steel parts using an electrolysis tank but am quite interested in your citric acid method. Seems to give similar results. If you could post some instructions that would be great.
As above, I'd get the old beam rebuilt as it will only be a matter of time before the other one goes. I've just stripped down my second beam. It wasn't giving any indication of problems and did turn out to be much better that the first but in fact the bearings had started to wear the swing arm shaft on one side. Once that goes too far I think the seals start to let water in and from there the deterioration is pretty quick. You seem to be pretty good at handling a spanner but if you need a hand stripping it down I may be able to help. I think you're fairly local to me aren't you?
I did notice a couple of things in your build. The bolts fixing the mounts to the beam were the wrong way around in one of the pictures with the beam off the car (left side). With the nuts on the outside they will foul the swing arm. I think you may have spotted that though as you've got them the right way around on a later picture with the beam on the car (but that pic shows the RHS).
Also, on the rear brake calipers the plate that locks the pads in place should go on the bottom and the springs on top. Welshpug has said in previous posts that with them the wrong way around they pads can pop out, which isn't going to make for a good day. I can't tell if you've managed to transpose the carriers on to the wrong sides but hopefully the pic below will help you work it out.
