i am interseted in the possibility of putting a sunroof in my 04 silverado (regular cab). i know that its not going to be able to slide back due to the lack of space. i dont mind if its just the kind that pops up in the back. i want to stear clear of the vinal ones. dont care to much about those. does anyone have any info on sunroofs in a truck? if so, let me know. thanks!!
