Caliper issues
 

Hi, I have what I thought was a set of 993TT “big reds”. When I went to mount them up to my 993RS uprights, I have a gap between the mating surface of the caliper and uprights. Looking at pictures of other big reds, it looks like the mating surface of the caliper is thicker than what I have.The part number on the inner half of the caliper is 20.5249.00. Can anyone identify what these calipers are and if there is a fix (spacer) or do I need different calipers. I’m putting all this on my 964 C2. Thanks.

I'm not sure what car those calipers came from, but it appears that they were manufactured in 1999. Maybe from a 996?

I don't know what they are but they are not 993 Big reds
here is what the mounting surface of a 993 Big red looks like

It's not a 996 or newer caliper either
