I converted an auto to manual in a Camaro- I know they are different, however the product from Hurst Driveline are straight forward and the support section is TOP KNOTCH! Am liked it so much I will do it again to my 73 Challenger from auto to manual. A big difference is that in the Challenge the Z-bar is welded to the frame, and the Tranny tunnel is much different, but they have a patch to fix it. IMO I say go for it, once done it is sure fun!!!
