Can anybody help to understand and recognize the difference between the brake calipers for a SWB S versus the normal brake calipers for the 911 (front and Back). I see that in the parts book there is a seperate number for the S version and L version but how can I see by looking to my calipers if I have the right one?

As the parts numbers are not mentioned on the calipers can somebody help me to understand were to look for? I see codes on the calipers but I can not refer them to any specification.

I am owning a Porsche 911S from 1968 SWB. I do know how to recognize the S calipers for the LWB version.

Many thanks in advance for your support again!

With regards,
