For reasons that I will announce shortly, I need to make a quick decision on something that I thought was a done deal. My car was built as an automatic, and I have a 518 I had planned to have built for it. Coming back from Tony Miller's today after dropping off a load of parts, I REALLY felt the need to bang some gears, and I started thinking about putting a manual gearbox in the Challenger. So, one of the things I need to determine is, for any of the Mopar 6 speeds, is there a gear set available to turn it from a 4 speed with two overdrive ratios to a close ratio 5 speed with a single overdrive ratio?
And while I'm at it, I assume that some sort of adapter is needed to convert these to an old small block?
