New to this site , I have a 1988 chevy k1500 / swapped trans to a turbo 400 . just bought for a project truck . I wanna change the head lights from the quad set up to the I believe it's the 93-98 style composite head lights my question is do I have to replace the core support to make this happen ? I know I will have to do wiring that's not a problem .any help would be appreciated .
