hi guys , i want to change the bumper and hood on my 1983 camaro with a later bumper(the ones with the nicer trim ) and the hood with the ridges(im not sure what you would call them) irocs have them , but im not sure if it would line up with the original fenders ,

 

It will be a direct swap. The 85+ bumper cover will fit just the same as your 83. If your car doesn't currently have ground effects, you will need to drill the holes in the fenders for them. The hood (the Iroc one with louvers) will fit, even with the 83 front end.
