It appears back in the day there were plenty of spun bearings with Max Wedges. I'd opt for a better pan. The closest spot is usually the RF inner flange of the K frame. I've had good success trimming the flange out in that corner. Many times it will make the difference between go and no go. Personally I'll never build another car without a enlarged K-frame. Even with my steering linkage going thru the pan and a diaper the pan comes off in 30 minutes.
