64 valiant 4 speed conversion questions.

I'd like to convert one of my 64 valiant convertibles to a 4 speed, 1 already has a 318 swap so that will probably be the one, it has a 727 in it now. I'm hunting for the floorpan hump and have a 69 a body 4 speed, it has a Lakewood scattershield that Is overkill so will find an alum. Bellhousing Questions are
Will later a body pedals work or do they have to be early?
Will later a body Hurst shifter and rods work?
Can a later hump work on the 64 pan?
