I really don't like thinking about costs. It gets downright embarassing.

Inferno TR15 - $230
Super10 Tank - $20
Optional diffs - $95 each ($190 total)
shocks - $50
graphite brake disk - $15
engine - $190
pipe - $60
front universals - $40
bearings - $30
engine mount - $20
clutch (flywheel, shoes, springs, bell) - $50

If I stop counting there, I'm at about $900 (all numbers are in U.S. funds) before misc. parts, body, and radio gear.
