Tomorrow Im going to look through a pile or two of banjo rear ends and torque tubes. I plan on making a set or two of headers and need to find some 36 or 37 drive shafts. I know anything 39 or later will have hydraulic brakes but how can I tell the earlier rear ends apart with out tearing them a part? Any help would be appreciated. Also a little off topic are the manual brake rears worth anything? I think I can get them pretty cheap and if I could sell a few for a profit it would help to further my project. Thanks again.
