As fer the tranny I have the 3.0 bell with left side slave but the tranny is a 1998 taco rightside slave. The bell bolts up but the engine mounted end of the 3.0 bell is 1 3/32" shorter than the 3.4L so I guess I will have to cut out a matching ring to weld up to the 3.0 bell unless someone knows a particular year of T100-Tacoma which has the longer bell housing and a left sided slave?
