i haven't read the article and i can't buy it yet in my hometown, I have a 71-74 bbody column, so theres no collapsing joints, just a straight shaft, I know with the box they reccomended the universal coupler : http://www.borgeson.com/xcart/product.php?productid=1724

i was wondering if one couldn't use a rag joint instead?

They had these rag joints on some of the columns to reduce vibration (i think the slang term was hockey pucks) what would be the superior one to have?
