Yep, the deluxe was just a trim package. I would however urge caution in trying to convert your small window to a large window unless you really know what you're doing. Remember these cabs have an inner and an outer. Buy an assembly manual and really take a good look before you start. Also remember to weld in steel structural support to keep everything aligned until you get the new roof/window section welded in because your going to lose a lot of structural integrity when you cut the old one out. Having never attempted this feat, I'm not really talking from experience, but if it were me, I'd plunk down a few bucks on a big window cab and just swap the whole thing out or else just replace the roof skin. I have a feeling that would save you a lot of time and headaches. Keep us posted.
