Gear Vendors question
The 2004R swap is one of the best mod's I've done to my '68 Barracuda, and it's definitely the best performing transmissions I've ever driven. I even opted to for a lock-up torque converter feature, which when combined with a high quality 3800rpm stall torque converter makes it perform like a 5 speed automatic.
I found the gear vendor's overdrive ratio was not worth doing for what I ended up with in terms of rpm drops on the freeway.
I don't like the crudeness and size of the Wilcap adapter and used a bolt-on bellhousing instead to fit a 2004R. I did have to modify the torsion bar crossmember, but not the floor pan itself.
