In terms of the pulley, could try a different pump. Ive had pumps where the mating flange is a different offset, to the one I've take off, where its not been pushed as far / or further onto the shaft.
Looking great though, one thing I've spotted in the last pic is the arch looks a little low for the side repeater compared to some sportspacks (just looked at mine)
Bet you can't wait for paint, such a good feeling building a freshly painted shell up
Hi Midas,
I believe this is a KAD issue, the standard pulley fits perfectly and aligns with the belt.
Regarding the arch - i've measured it up against a mate's 500 and its bang on, it is often thrown by the fact they don't have the rubber seals on.
