i'll have to dig thru some pics and check photobucket, but yes the 86/87 rear fenders do fit the 84/85 t3. with modification. you have to cut the back part of the seat pan on the rear fenders in order for the seat to fit correctly, and latch. they look ok, a bit big i think, but not as good as a set of oem 84/85 fenders. search for biggreenmachine. james has a set or used to have a set on his 85 t3. not sure what he has now cuz i havent seen him on here i quite sometime.

Life's journey is not to arrive at the grave safely in a well preserved body, but rather to skid in sideways, totally worn out, shouting "HOLY SH-T, what a ride!"
