I have always purchased used tilts from the 60's. No key type. $125-$200 (Craigslist). Most all Chevy wheels fit all Chevy columns 40's to 80's + . Also, a rag joint, instead of Ujoint, will only work if it's lined up almost dead nuts. Rag joints are for vibration dampening only, not to function as a Ujoint. You probably need ujoints and a DD shaft.
