then I found out Tacoma with factory 15" wheels the brake swap wont fit my 15" steel wheels   

I had to add a  1/4" wheel spacer to get my calipers to clear on 15" steelies.  I'm planning to move up to 17" once I'm finished and hoping that will fix the need for a spacer if not there is only a little bit of grinding on the caliper that is needed to get them to fit.

My fror full float on the rear is worse and I had to add 1/2" spacers to get the 94' IFS calipers to clear.  Again, hoping that the 17" wheels will fix that and if not should be able to grind a little off the caliper to make it fit.
