Since this is my first kombi gearbox I cant compare it to anything
cheers

002 3-rib is the original bay gearbox used with motors (1600, 1700, 1800) through 1973, and on (AFAIK) 1600 powered bays up to 1976. If you look underneath it it will have 3 transverse ribs moulded into it across the transmission case.
The 002 5-rib is the gearbox used with 1800 and 2L motors in 1974-75. It is geared slightly differently to make better use of the 1800's higher power and torque output. Cant remember exactly what the diferences were but I get the feeling 1st is taller, 2nd is closer to 3rd and the final drive is a higher ratio... or something like that. It is pretty much identical in dimensions and construction to the 002 but has a total of 5 ribs moulded across the case underneath.
CHeers!
