is it possible to replace just the tumbler in my ignition switch? I purchased an aftermarket ignition switch, gas cap and seat lock set for my 1998 TLR so I would have 1 key that fits all. unfortunately the ignition switch does not fit because it only has 4 wires where the factory has 6. I was thinking I could take the tumbler out of the new switch and install it in the old switch of anyone could tell me how to remove the tumbler from the old switch. thanks for any help.
