Dougs and spool mount in 72'?

I have a set of Dougs D453 in my cart from autozone with the 20% discount. I just want to make sure they will fit before I pull the trigger. I have done some searching and I believe they will fit, just not sure because of my application. I have a 72 swinger with a 360, 727, console, power steering. By issue is I have a spool mount k member, not sure of year. I do not know if I have the the 72 steering linkage or if it is from a later model like the k member. Any one running something similar to this that knows if it will fit?
