Don't do it, Les.

The steel adaptor not only adds weight to the piston it also shortens the 65mm stroke, a better bet is to buy a complete synthetic sealed piston --- Knibbs had them on offer a while back

The synthetic sealed piston has a 4mm longer stroke than the leather sealed piston.

If you get stuck I'd be happy to collect one and post it to you.



All the best Mick
