How to measure your g260 output Flange

Unless you send in your core beforehand, all Condor Getrag G260 rebuilds require the measurement of the output flange on the original G260 transmission.

The smaller size flange & guibo was supposedly used up until 4/86 - after that the larger size was used. Do not assume you have a smaller guibo because of the year. Use the photos below as a guide to measure the distance between the two flange holes as pictured below. 

The smaller size flange measures 68mm uses a guibo that measures 110 mm in diameter - the larger flange measures 83mm and uses a 135mm diameter guibo.
