hi i've got a 1982 leone GL 1800 (aus model), and was wondering if i could do a few conversions for it. firstly ea81 - ea82t, this should be a bolt in job? anything special need to be done for this conversion? secondaly auto - manual, is this possible? once again anything that i should know about. thirdly 2wd to 4wd - i've herd that some late 80's 4wd running gear will bolt in without any major hassles and the only major thing is fabricating a rear diff hanger, once again any ideas? cheers.
