Ok, I have an original 70 RT Charger 440 Magnum/auto car. I'm growing rather tired of the 727 with no overdrive. I'd really like to put a late model 5 speed manual in it.

My car has clean original floors, so I want to keep permanant modifications to a minimum, but I know a piece has to be cut and replaced for the 4 speed hump.

My question is, what is the best (And least destructive) way to convert this original auto car to a manual trans? I hate to modify an original RT, but I'm never selling it and it would be much more fun to drive with a stick. Not to mention overdrive.

Is Keisler my only route? I've been offered a complete 833 pulled out of another Bbody, with pedals and linkages and everything, but then I still have 40 year old parts with no overdrive.

So what's the best way to go about this? And does anyone have a rough idea what the Keisler kits are going for? Or has anyone here had experience with one?
