[oletrucks] 3 speed floor shifter?

[Williams Grant Civ Det 2 418 FLTS/ENQA]

Anyone know of a aftermarket 3 speed floor shifter that will work on the
47-50 Chevy trans with closed driveline?  I'm seriously considering getting
rid of the column shift on my 50 GMC to eliminate all the linkage and
adjustment headaches.  I saw a Mr. gasket kit at Pep Boys that claims to
work on 55-62 chevy 3 speeds??
