Okey the bearing is a Team Losi Performance part number A-1508 and the description is rigid steering arm set. The bearings comes in 4 pcs. per set @ $ 29.99 but got it for like $20.00 coz somebody hook me up.
The magnet are rare earth magnets from Radioshack 2 pcs per set @ $ 1.88.
The drilling can be tricky because you have like hair thin left in the trigger as the pics show. But it was a very good upgrade.
