Finished the fork rebuild/seal replacement. Need to take it for a ride at some point to see if it's improved the front end (if not am thinking steering bearings...).
Discovered a few tips for doing this. First put the oil lock piece and the rebound cylinder before installing the bushing/new seals (I ended up having to strip it back down as the oil lock piece wouldn't go through the bottom of the inner tube by dropping it in - Pic of the offending items below)
The homemade seal driver (thanks to Delboy's garage) worked really well for seating the bushing, though I found the electrical tape method better for pushing the actual oil seals in.
