mk1 / mk2 front strut tops

[s13eater]

can anyone shed any light on this, i'am having problems, i've taken my kyb inserts out of the mk1, they where in some struts that turbo mike gave me, but i've put my inserts into the coilover conversion, i used the struts off of flex's mk2 ,only to find that the caps wont fit over the inserts, are the mk1 and mk2 threaded tops that hold the inserts in different.if so has anyone got a spare set with the thinner sidewall.cheers.
