my buddy's TH400 took a crap on him the other day in his 87 R30 Dually, so he's looking to put the spare 465 he's got laying around in it. he wants to convert to a hydro clutch, since he has the pedals laying around. i've located a bellhousing for the project. will the mechanical clutch fork work? or will it need to be changed? how about the throwout bearing?
