I just got an unbelievable deal on an FX4 gauge cluster that has 500 more miles on it than my truck does now. Won't take me long to rack up 500, then I'll swap them and finally have my FX gauges. Here's my question.....are the clear lenses on these clusters interchangeable from an XLT to an FX? The lense on the one I just bought has a nasty scratch in it, but I could not pass up the deal, no way! My XLT's lense is flawless, so I'm hoping that I can swap the lenses on these. What do you know?
