I'm changing the multi function switch in a 95 cherokee. The cover beneath the steering wheel is fastened by T20 screws. The switch itself is also attached with torx screws, but t15 is too small and t20 is too big. I don't see any in between sizes, so what am I missing? Thanks.

 

Go to an auto parts store and try one till it fits.

 

Try to find Torx TX drivers, they might have a slightly different fit.

 

Some of the bigger bit sets at harbor freight will have the odd tweener size torx bits. Also, lowes and home depot now carry individual bits and they are a lot cheaper than the the individual/singles at sears.
