you will unbolt the rag joint and there will be a DD end under it.

then its a matter of getting the right size DD u joint, should be 1" at the bottom of the column shaft, the u joint will be one size on the one side and either the same size or a different type on other side. I recommend a 1" DD to 3/4" DD u joint for right off the column.

then you will need a piece of 3/4" DD shaft.

then at the steering rack you will need a 3/4" DD ujoint with the other side splined to match your rack.

prepare for some sticker shock, u joints arent cheap, and being cheap on steering (or brakes) is a stupid way to die anyway.

if thats all you need then great, but my advice is to get the motor and especially the exhaust manifolds on. I just did steering on a 53 for a guy and it took a double u joint, a regular u joint, two heims, two chunks of 3/4" DD and another u joint at the rack to snake around the exhaust. it was over $400 in parts.
