Affordable 5 or 6 speed transmissions?

I did the Hurst Conversion TKO 600 kit. I called and nixed things I didn't need like a clutch (just buy a 26 spline disk), hydro system, throw out arm (you do need the bearing) flywheel, etc. My stock 4 speed to 8-3/4 drive shaft works, just bought a 1330/7290 u-joint conversion. Its all in, buttoning up the tunnel now......slowly. Great kit, sales was helpful and I got what I needed.
