What trans to use?Hugger Orange original?

[new271]

Bought a Hugger Orange 1971 2wd shortbed,v8(307),3 spd a few months ago(I'm 3rd owner),The only thing changed was they converted to HEI and the column shift to floor shift. 3spd shifts sloppy and jams.Should I keep the 3 speed and maybe get a new shift unit or go to a 4 speed? Looking for a direct bolt in swap. Also the sticker in the glove box shows the paint as Hugger Orange(and that what it is)But I haven't seen many.Is that the correct color? Any help would be great.

I'll have some pictures later.

Thanks
Mike
