anybody has or know where i can talk to someone that has installed a 6 speed manual trans in a b-body 69 road runner

I'm planning this conversion myself. From what I've gathered you can expect:

Hydraulic clutch cylinder will need to be hung.
Trans tunnel modded substantially.
Torsion bar crossmember trimmed and modified considerably.

The other stuff is a given like quicktime bellhousing, custom driveshaft, etc.

let me know if you get more info torsion bar cross member not a issue no torsion bars run on the car the tunnel how far up to the fire wall? that's would be very helpful i know the tunnel will be raised and widen.i was told that dodge charger web site is installing one i think a viper 6 speed but have not got on site yet.

Im one of the guys installing one on the dodge charger web site. Plan to completely cut out the trans tunnel and raise/widen it by 2". Torsion cross member also has to be partially removed. Mine is behind a Gen 3 viper motor, however.

There are 2 builds on site - a 69 charger and my 70...
