Outlaw motorsports stated in one of their posts here that a 14.75" x 2.? x1?? is going under one of their turbo phazers. What does that mean? Well a mod shop has already been in there and 15 will not fit. There are a number of techniques to narrow a 15 (the width that there is the most choices) and I am liking the table saw method the best. FWIW.
