Locating a '67 Chevy 4-Speed Shift Boot

[Sandemonium]

Hello,

I have tried searching both here and Google, but I am having a difficult time trying to locate a shift boot for my application.

I recently bought a '67 Chevy 2wd Shortbed with a I6 (250) and a 4-speed (SM420). I plan on keepting this combination for awhile, but the current shift boot is not sealing at all.

The measurements of the current shift boot is Base=6.5", Top hole=3/4", Height=2.5"

I have checked locally and with a couple of vendors online and they all seem to offer a boot for 68-72 in different configurations, but no round ones.

Does anyone have any reccomendations on where to find this shift boot?

Thank yuo,

Bob
