So, reassembled my front end which is looking good, thanks to the previous inmates for help with that! Got the rear wheel on fine, perfect etc. The only trouble I have is that the front wheel was extremely tight fitting, so much so that I had to spread the legs to get the disk though. I've just been out and measured the alignment using a not very scientific method and they are pretty much dead on, i.e. within 1mm between very top and very bottom and straight all the way down. Is this normal? It looks like the axle when fitted will align the wheel centrally but I suppose to really check I'll need to fit the callipers again. 1983 R80 TIC btw.
