ke70 is cable clutch dude. no one except nick!! has ever gone from AE71 to KE70 spec.
ae71 gear goes into an Ae71 so i'd say you can get all the ke70 stuff into an ae71. may have to put the clutch cable in a diifferent spot as there is a hole for the clutch master on an ae71 where the cable goes through on a ke70.
hope that makes sense, i am a little sauced......
wh yare you doing this? i'd be keen on soe mae71 shit
