Hi
I got these parts and want to confirm to what year they're made for.
I found those numbers on our host but no further description.
Guide tubes 950 116 81301
Caliper piston 93035255501
Caliper piston 93011681306
Thanks

93035255501 is a rear caliper piston for '78-'89 911

The other two numbers come up as "part number unknown" in the PET program.

Hi
Thanks for the help. The other caliper piston could be for the front, I will go to see my mechanic today. The guide tubes in the picture is a little larger in diameter and that could be for the pre 89 turbo.
