91 b2600i ignition cylinder and lock set

I need a cylinder and lock set for my truck. I see some on ebay listed as compatible for a b2600, but when you go into the listing and put in a 91 b2600, it says it is not compatible. Are the cylinder key sets compatible between a 1991 b2600 and b2200?

I bought a pair of door lock cylinders from Rock Auto for my B2200, work great. You re-use the little plastic clip from each side. So you may want to consider getting a set of those and then getting the ignition lock cylinder keyed to match. See

I never did bother to get my ignition cylinder keyed to match the new door lock cylinders, so I have separate keys.

On ebay there are ignition cylinder and lock sets that are for a b2200. Will it work for a b2600i?
