A little Stereo help please.
 

This is my first post and I appreciate your help. I just purchased a 1998 Ford 150, 2 door, Lariat with the 5.4 motor to pull my bass boat (and it sure does, nice and strong motor). All the speakers are blown and I would like to replace the head unit. I looked at a couple sites and one should single din for it and the other showed double din. Does anyone know for sure? Also I believe the speakers are 6 x 8, is this correct? Will any others fit? Thanks again!!

Oh boy, just read the Sticky above and it answered all my questions. Should have done that first.
