I will use the 49' and cut out the old spring perches and replace with new spring perches with two holes in them. That way the emergency brakes and ect. will still work. I will clean up the 3:73:1 rear gears and swap them out. Should help on the gas mileage also. Just thought I'd let everyone know. I'll try, I say try, to get some picture of the conversion. Take care everyone.

The only gear ratio upgrade available is a replacement gearset in 3.55:1 ratio that's sold by a couple of antique parts vendors.
