Found the easy way to get the pinch bolts off.
Tools :
Lump hammer,
smaller average hammer ( with a flat or ball ended tail end)
spanner ( what ever size yours is )
deep socket ( again what ever size yours is )
Punch tool ( no bigger than the diameter of the bolt )
Breaker bar or large ratchet spanner ( may need adaptor for socket and a extension bar.
Get socket and adapter on breaker bar nd place on nut , place spanner on bolt head.
Crack the nut off with the breaker bar whilst still holding spanner on tether end.
Once the nut starts slacking off, change socket to rachet spanner and take nut off completely.
Re do the nut on a few threads, then take both hammer and lump hammer, place hammer on nut face, hit the hammer rear head with lump hammer unit the bolt has moved all the way through til there's no space between hub and nut.
Take nut off again, and the proceed to push bolt through will punch tool.
If done correctly with care and force
the bolt should fall out the other end.
( ps, that's how I did it, you may find an easer way )
