For sale is a pile of Columbia parts to convert a 1939 Ford rearend and a 1941 Ford rearend. As you can see in the pictures there are two axle housings for the 1941 (sandblasted) and only the special one housing for the 1939 (unblasted). Both Columbia sets will require donor original rearends to use many parts from. But, I think that all the special Columbia stuff is there to create two rear axles. Note: There is no dash or vacuum controls from the engine side here. Only the rearend side. Please look over the pictures closely and note the condition. I found the A-24 Differential Case is cracked on the one I disassembled, like most of them are. I have not examined or disassembled the other center, and will leave that fun to you. I bet there is a cracked part in there as well, since most of them are. Also note the condition of the axle housing bearing races. Some guys would run em, others would require a race sleeve. Up to you. Price is $600 for the whole pile, handed to me as cash when you pick them up in Marshalltown, Iowa. I will not be shipping these. But, I will be going to the Twin Cities Roadsters swap meet in a couple weeks and could deliver up there if you are a trustworthy fella. Let me know ASAP. If anyone needs another pic of something in particular, send me a PM.
