#1984

I have a 1984 grand Prix that I want to make into a widebody,I want to get wheels that stick out but Will a 15x10 negative 44 or negative 39 Offset wheel fit my car without rubbing? /my car is not c notch'd I also want to get a 255/60R15 102V Tire

i have a 4.8 ls swap that I’m going to put into my 1984 Buick Regal and I was just looking for tips and recommended motor mounts and will the motor run just off the computer that I took out of the truck with the ls? and how will I get my speedometer to work again I’m just trying to have a turn...
