Your Rally looks great with the titanium bolts, your model looks a little different with the Record letters on it, is it modified with parts from other campagnolo models?
First, I have read and seen pictures online that the difference between the two is: the reinforcement at the back, (the one without is the oldest, as you also mention) and then I can see that the oldest has campagnolo letters on the back and has numbers engravedon the arm, the new one doesn't have it. Thats the only things I know.
The "newest" model of the two rally´s, I know it has never been taken apart, as it has been sitting on a one owner bike from 1983 that has been in a garage for 40 years.
- It feels right and have a great tension / pre-load.
The slightly older model I had bought second hand,
and I thought the angle of the arm looked a little wrong, without being an expert, but I bought it anyway. I don't know the history, so it may very well have been taken apart over the years.
I just tried to take it apart. It feels like it have to much pressure / load compared to the other rally, although the arm does not turn all the way down as it should, if I move it more forwards its very hard, I think the arm with the spring has been turned to much around or 1-1˝ turn? Otherwise it totally loose, but still not in the right position.
I tried to change it in the hole, and it does not help. I can't get the arm to turn downwards and fit the correct place where the stop-screw is.
The arm has a lot of pre-load, or otherwise is complety loose.. The spring looks i bit worn out??
.
Sorry I don't have time to fully analyze all that, but I will say that bent spring can be replaced, probably easier than straightening it. It's the same spring as on NR, Nuovo Gran Sport, "980" and a couple others. Shouldn't be hard to find a usable replacement, like cannibalizing a crashed/bent NR.
The weird mismatch between your cage and the spring cover angle may mean one of those parts has its holes drilled in the wrong place. (Did they change the location of those holes, from the older to newer production? I wasn't aware, if that's the case.) Take the other one apart too and see if you can see which part is different from the others. Drilling one new hole in the right place will probably fix it. Drilling the spring cover will be eaiser, since the cage has that steel nut that's pressed in place, wich causes the drill to come through partly in the steel and partly in the soft alloy. That makes the drill want to wander, potentially catching or snapping from the side load. Obviously do-able, but I'd still choose to drill the spring cap.
