i used a 50 chev truck bellhousing.cluth plate from 85 astro van.the clutch housing was 54 chevy as was the flywheel.as for the trany mount i fabbed a crossmember in about ten minutes that works well because i used the truck bellhousing mounts.this is as smooth as it gets without going 700r or 200r.i was going 350 turbo but that was too costly.the t5 swap was under 600.i nused a salvage yard gearbox and everything else was new.you will need to have300plus gears in the rear.if not it will drop to nothing in od.i went with 370's.it cruises with the boyd cookie cutter cars and was built in my garage.that tears them guys up....a 25 dollar motor and a running gear for under 750 including rear..i just keep buzzin right along.
