Gas Tank Skid Compatibility

I have already searched this, but does anyone know if the 97+ gastank skid will fit a pre-96(89) without modification. I found plenty of info to put an early skid on a later model but didn't seem to find anything for the other way.

97+ skids are harder to find, sell it to someone with a 97+ and get one for your year.

No, they have to be widened. JIM.
