Can anyone tell me the easiest and most budget conscious 4spd to 5spd conversion for '65 C20 with a 230 cid? Trying to make this a good daily driver. I was just going to change the gear in the rear but I'm having trouble finding anything for the heavy duty Eaton. Think Art Houser's got a 3.90 gear($468, WOW!)so thought that coupled with a newer 5spd would be pretty nice. Anybody gone thru similar situation?
