4 SPEED HUMP FOR 64 VALIANT
It's worth mentioning that the Brewer's part is a reproduction of the 1966-only floor tunnel.
The 1964-'65 tunnel had a smaller riser around the shifter and used a small round boot and retainer/bezel (and in some cases a decorative plate with the 4-speed pattern). The correct early hump can be seen here. Good originals can be difficult to find; perfect ones can be expensive.
The 1964-'65 boot, retainer/bezel, and shift-pattern plate:
The three items pictured above will set you back about $400 total.
The 1966 tunnel uses the same oval shifter boot setup as the 1967-up A-bodies. Those parts are more easily found and much less expensive, so it's really down to whether you want it to look factory-original. If cost is a big factor though, Brewer's fiberglass piece is probably the best option.
