steering column rebuild in progress

That looks like the column I just got done rebuilding but mine is a 73. You can still get the upper bearing from ebay or a couple mopar resto sites sell them for about $30. The lower bearing is a different story. Yours is going to be in a metal sleeve with the bearing inside. You can get a similar replacement bearing from an 80's full size dodge van from the dealership. It wont look exactly the same but it should work.

Get a factory service manual or do a search on here, you can find the steps involved of disassembling it.
