Put the servo off an early 90/110 - this is a 9" unit not 8" as is std. You have to make and adaptor plate and swap rod ends, but it goes on with no bodywork mods. Drops pedal pressure about 20%. The 9" servo is actually cheaper than the 8" and the BP ones come with a threaded rod so its easier to swap parts. I also fitted Borg & Beck shoes, I did a lot of research and these are a lot softer and better friction, follow the "my brakes are cr@p" thread as the OP is about to fit them and we we see if they get the same improvement, so wait till then. I also fitted braided brake lines, honed the cylinders/ and new seal and master cylinder. Replaced worn adjusters too and all the hub seal and lands. I think they now work as well as any drum set up could and its made driving much nicer and more relaxing.
On the steering front I greased all teh rod ends, topped the relay up and shimmed the steering box (in-situe), the shimming took at least an inch of play out, probably closer to 1 1/2" which also makes keeping a striaght line a lot easier.. Its been a busy lock-down but with no work its been a good time to do all these jobs.
