#2405496 boot is 1963 (only) with the Borg Warner T-10 4-speed or T-85 3 speed. The slot for the handle is not centered in the boot, like #2405552, the 1964-65 non console boot. We have a repro of the 1964-5 boot: http://brewersperformance.com/proddetail.asp?prod=SB552 I have never seen a "H" on any factory boot.
