Oh hey, look what reading the manual gets you, the part numbers for the uprights:
'04 Lower Brackets:
Front:
SPS15-H4080-R
SPS15-H4080-L
Rear:
SPS15-H0482-R
SPS15-H0482-L
'05 Lower Brackets:
Front:
SPS15-J3953-R
SPS15-J3953-L
Rear:
SPS15-J3956-R
SPS15-J3956-L
What's stupid is that they gave the '05 rears new p/n's even though they should be identicle parts, since the knuckle they attach too is unchanged on the car.
I wonder if I can just get one of the bigger resellers (Gruppe-S, MPJ, someone) to order me just those parts by number. I don't think C&C will have much luck 'cause C&C is pissed at Tein due to pricing issues.
