cheapest way to convert to manual steering?

hey guys,

id like to convert my power steering to manual steering without breaking the bank...I know i have a manual box somewhere in my garage although im not sure what year vehicle it came out of (do they all interchange? i have a 71 if that helps) and id like to use it with the least money and modification possible. I know that certain mid 70's-mid 80's vans used a coupler that adapter the same shaft to a manual box, but im wondering if theres any other ways to do it? id rather not spend the money on the mancini adapter that they sell since its kinda expensive at 125 dollars, and i dont really want to lengthen my shaft either. Anybody have any suggestions? also, are there any other parts i would need in the swap that i have forgotten here?

thanks!
Matthew

I think you pretty much covered your options, If you don't want to spring for the adapter, your other option is swap the column to a manual column. 66-76 box will work.
