Hi Ian,
A2 is here now and I have a Terminator on it's way (resisting "I'll be back" jokes!!). The Genesis looks to be in excellent condition so may be available shortly. It has the 19mm shaft end so, IIRC, that's AMP suitable. I'll do a pressure test in the interim and a full check when the bike is built up over the next couple of weeks. If you have any dimensions off your current shock I can double check them to see if it is suitable.
Cheers
John
