The holes for the seats are the same, they will bolt right in, as for wiring up the power, if i remember right there's a 4 wire plug on the 99 seat, just cut that off then the two green are power and the black is ground and the remaining is for the seat belt light which u leave unhooked. Een if your car does not have pwr dr. seat there should be a plug with power and ground under there. I've got 00GTs in my 93 coupe and they bolted right in, any other questions just ask. Hope this helps
