I have a 4-speed toploader HEH BW 017171 / C5AR-7006-D W-2 that I am looking to sell to a friend. What would be a good asking price? I have placed new gears and sychros in the tranny via David Kee Top-Loader. It has 3000 miles on the tranny since rebuild. I am looking to go with a 5 speed TKO for greater acceleration and gas mileage. Thank you for your input.
