I know things changed in 73 on the B-bodies. Do they use the old coupler or a rag joint like the Cordoba?
They both use the coupler & the rag joint. The difference in the 73 and 74 is the location of the rag joint. In 74 it was near the firewall in 73 it was at the steering box.
The coupler is supposed to fix alignment problems with the steering box and the rag joint flexes with the K frame since it is on rubber biscuits. Or so they say.
