68 Skylark Tranny

I have a st300 2 speed tranny and would be interested in swapping up to a 3 speed.
The engine is a 350 2 bbl. Its a base model hardtop body.
Does anyone know if there is a tranny that will do a direct swap, or would it just be easier to rebuild the st300? It slips really bad now. My wife bought me the car for xmas last year. I have replaced the drum brakes with discs, replaced the entire fuel delivery system front to back, and have the engine running like a top now that I changed the points, plugs and wires and learned the right way to set dwell. It will be a hoot to have on the road more often once I fix tghe tranny. Can't cruise it now, I'm concerned the tranny will give up the ghost when I'm far from town! Any advice on the tranny would be appreciated!

Check with the major performance rebuilders, a 350 trans may fit with a different flywheel, convertor and crossmember, common swap it seems.
