The parts book list two different part numbers for the 36 rear axle housings and both are different than the 35. p/n 601932 for model R with mechanical brakes and p/n 602233 for hydraulic brakes. The propshaft to differential are the same as 35. Axle shaft is 36 only p/n 593066 (36 & 1/32 in. long). Rear hub, bearings, brake flange and etc. seem to be the same as 36 to 39. It seems wheel are different from 35 to 36 (offsets). 36 axle ends would be different than 35.
