Should I do the conversion to the green one? I want to put the 2F 4spd and the axles. Add a holly 500 and header to the 2F. Did anyone run into problemes with spring pertches on the newer axels? I want to do this because I found a 60 daily driver for $1200. It has a rebuilt front axel. I want tobe able to cruise crosscountry to go to some events in Cali. Thanks Shawn
