Our factory flat domes i feel leave a lot to be desired. I dunno if its been covered but just so anyone that wants a change knows u can use a suburban dome but it has to be the rear dome. 2nd row hangs down from the headliner and mount holes dont line up. Leaves an ugly gap at the rear of the housing. Ill try to take some pics for comparison so everyone can see the difference And if anyone is lookin for em ive let hobbs and cokeman know since they seem to be the go to guys for junkyard parts. Plus this looks really good with whichever factory OHC u go with. The wiring i wont get into cuz i hate electronics and dont want to give bad info.
