I admire your restraint in staying with Shimano for most parts. You'll be rewarded with a bike that works well. Nice fix on the brake bosses. Amazing what people will do...
What, you mean so I can actually use the pedals .......dont be silly
Front wheel is on the right way. Owned the front hub since new (93 I think). The rear (pic below) I picked up from Ratcapa on here. They are an 8 speed set but as the bearings were shot anyway I rebuilt the rear with a 7spd Freehub instead of going for spacers.
