heh i love the eIII... they worked well for me, took it to TCS
Did sell off some cars but still got fair fleet left in all 3 colours
plus a red kit autographed by Surikarn whilst he was World Champ
shouldn't be too hard to piece together a balldiff,
most parts are common bits except for diff outdrives
eIII outdrives
eIII balldiff gear
2x 850 BBs
M2x25 diff screw & nut (u can even use yokomo or 3Racing parts)
thrust bearing ( "" )
spring
diff rings... i think they're F201
3mm balls (not needed for spool)
Cut some cardboard same size as diffrings for spacer between diffrings & the gear.
if u can, buy the BLACK outdrives (from TBeIII) which are
cheaper & less brittle than the white TBeIIISE ones
avoid buying TB02 diff outdrives unless you have really no alternative,
the eIII parts were unable to find few yrs back but have since reappeared
Spool mod here if you need
