T-Handle?
 

How hard would it be to install another Bonneville's stock T- Handle shifter-knob to replace my stock cobra-head knob. Would it just slide on? Are there any specific years that would work better?

It should work just fine, but the shift boot would be a little short if I remember correctly. Just pull off the pin on the front side of it with a screw driver and then replace it with the T-handle

How does one replace the boot?

actually the Boot is longer for the Cobra IIRC, so the T will fit just fine

The boot is guled to the underside of the center console. It's a pain to pull off and near impossible to glue back on .

If you'd like I have both shifters laying around and can take pics. BTW..the T handle is longer and requires less boot. Therefore you could swap to a T w/o having any issues. It's the cobra head that is shorter and needs more boot.

Ah ok, I gotcha, easier to switch from cobra, not to cobra. Anyone have a T handle not in use and would like to sell, or have any idea how much I would pay at a yard for one? Also, are there any variations in the styles of T handles from year to year?

Bill - Sure if you don't mind taking pictures that would be cool. Thank you much.

When I take pics..you want me to pack it into a box for you? ;)

Pm on it's way
