Does anyone know if all rear bumpers (stock) are the same? On parts websites, I see different numbers depending on what wheels came with the vehicle. What does this mean? Thanks

 

For 2nd Gens, the sizes are the same, but they were available in chrome or a dark grey paint. Maybe that's the deal with the different PN's. The grey paint bumpers were on the el strippo base model I think - which would have had steel wheels. Chrome bumpered models had either alloy or steel wheels.

Hope that helps.
