Steering column Intermediate Shaft?

[chevmech1969]

usually i put the isolator on the rack, and i use the set screws then weld on the flats, i wouldnt weld on the one with the isolator. and using a solid shaft is ok, the collapsable one is kind of a saftey if you smash into something the shaft will collapse instead of push the steering column up into the pass compartment.
