Educate me on R&P

I need some 'exposure' to R&P configurations.

I have numerous cars and tranny and would like to know:

1. R&P on an '83 SC. (on the car)
2. on a '77 911S. (on the car)
3. 197x 915 magnesium tranny.
3. 86 930 tranny.
4. Factory short-bellhousing 930 aluminum tranny (197x).

Do R&P numbers affect the 'speed/signal' sent to the speedometer?

Is R&P same as 'gearing?' (tall/short)?

(stupid question: R&P cannot be known unless you take the tranny apart, right?)


Can I decipher the 'year of make' based on serial numbers? How?
