how to determine caliper part numbers
Need some help. I have some black front calipers that are from a 3.3 turbo and rears from a 993. I cannot find a part number on either only casting numbers that are on the inside of the caliper just outboard of the pads. The fronts have a large font 92 with a casting number of 20.5248.00 on one side and 20.5249.00 on the other casting..the rears have a lg 94 with 20.4673.00 on one side and 20.4672.02 on the other side. Any help would be appreciated.

If you know what you have why do you need parts #s?
anyway, here they are,
3.3 965t fronts are 965.351.423(4).01
black 993 rears are 993.352.421(2).00

thanks for the reply. i should have stated that they are new to me and just trying to confirm exactly what they are before I have the car apart to replace the original calipers. also the rears came without pads and want to make sure that I order the correct set. on an associated note the rears need to have the dust boots replaced and it is clear where they fit but where are the pressure seals located? on the piston or in the cylinder bore?
