I disassembled a 1950 4-speed trans just for kicks and to clean it up and check it for wear and possible bad bearings. I'm putting it back together now and I noticed that the reverse gear fork rail has one end made of brass. I'm just wondering why that might be and whether it makes a difference in which way it should be re-installed - brass or steel end first. I didn't pay enough attention during reassembly, but I think the steel end gets inserted first which puts the brass end at the rear of the trans. The shop manual doesn't say except it does say that the rail should be installed from the rear.
