When I bought my '70 Jimmy the front seats had been replaced with high backs. Now I'm not that big of a guy, but the steering wheel seems awful close with the seat in the furthest back position (maybe too much holiday food?!?!?!?!?!). I'd like to know what is the best option for tilt steering, or is it possible to shorten the original column? I may have to look at modifying the seat bracket to get a little more clearance. Also, the rag joint and bearings on the shaft are shot, will later models bolt in?
