hey all I am in need of some help on mainly the removal of one of the lifters in a 929 i am fixing, it seemed to have a colapsed lifter as the the whole rocker arm had dropped down and was quite loose. i have bought a new lifter for it but cannot get the old one out, have tried pulling it, it will spin but doesnt seem to get any further out, i also noticed the new lifter has no ball/pivot on the top....does this have to be swapped over from the old lifter?

any help will be much appreciated, Cheers Ryan
