You got a good deal. The upgrades are limitless for that thing. I would get a better stronger steering servo, rpm arms, integy rear hub carriers, golden horizon bell crank, ofna throttle mod, flux or xl bp diffs & shim them, extended xl cups & dog bones, ditch the roto start for a pull start, lighter wheels & lower profile tires &last an ERCM modded motor & 221T end or side bleed pipe. Stay away from a lot of aluminum parts as they will bend. I know its a lot but that's what I would do.
