Yeah RP is very used in France for parts, but looking for better price x)
Rose Passion - P48433 - 98633202455 - DRIVE SHAFT - Porsche Boxster 986 2002 Boxster S 3.2 CABRIO MANUAL GEARBOX, 6 SPEED > REAR AXLE ASSEMBLY > UNIVERSAL COUPLING AND BELLOWS
part is 700€, x2 if I repare rear. I dunno if it's a correct price or if there is better.
And that's why in first place I was looking for part rebuild x)
