So as you can see the mk1 spring sits nicely against the stop and the stopper arm retains the spring on the right hand side, while the mk2 spring is a different shape, it's bent (straight according to fiche) but the stopper arm retains the spring on the left side !!
Also the mk2 spring is wider by a few mm where it sits on it's stop so that makes a difference when fitting, i've tried a few ways using mk1, mk2 bits together but it's locking up the drum selector, dogs on the input shaft are in neutral on the drum and the output shaft dogs are waggling in the air..the dogleg shaft for the output ( 2 dogs) has a spring on the mk1 but not on mk2, i wonder if this will make any difference to gear change !!
Wondering now if this washer/spacer (middle in pic) should'nt be on the inside of the bolt for the stopper arm, i did try it but drum is still locking up when it's all bolted...

Any piccies of said parts on a mk2 would be helpful, Haynes only shows mk1 fitting and have me own photo's but mk2 gubbins looks a but queer 
Mk2 spring looks straight here, so have i got a bent mk2 bit ? the spring leg where the number 14 is on mine is bent.
