Auto Floor Shifters

[Diablo de la Noche]

I have run into a dilemma. The PO took off the column shifter and bolted in a cheap floor shifter with no safety catch. You just push it and it goes into the nearest gear. Not so bad if it were a manual transmission. This has made my automatic shifter truly automatic. I have searched summit, hurst, etc and can't seem to find the right shifter for one of our trucks, everything seems "geared" for cars. I love the Locar models, but that just won't fit into my design for a semi-classic (mid '70s) style hot rod.
Does anyone have any sane suggestions as to what I should be looking for in terms of the type/model of auto shifter? I have a 700R auto hooked to a 350 (1986 vintage).

BTW, I did search the threads but couldn't find what I needed.
