Universal steering couplers

on a 65, the column is held on with a 2 bolt strap at your knees! A rigid mount would just slide the steering column in and out a few mm's. If your welding...how about a 3/4 drive U-joint? Weld a socket on the steering shaft and have a removeable "snap in" column.....nuts? You AINT gonna break it! (4000 in/lbs)

Looks like weldable steering U-joints are cheaper than these......
