These are from my car (in CAPS), but hopefully they should be the same:
Catalytic converter: MR160227
Brake disk (FR): MB895097 or MB928319 (it lists 2 for some reason)
Brake disk (RR): MR128734
(doesn't have one listed for LF or LR, they're probably the same)
Torque converter: Doesn't have a part number listed, perhaps because my car is a 5spd manual
Engine mounts: These are made up of many different components, but these are for the brackets themselves:
Bracket - transmission mounting body: MR297694
Bracket - engine roll stopper RH: MR333022
Bracket - engine FR mounting: MR297532
Bracket - engine roll stopper LH: MR333023
Maybe someone with a GPX auto (or at least a chassis number from one) might like to confirm this, because I'm a bit of a noob when it comes to CAPS
