Here you can see my RS conversion from beginning to end.  My driver fender was already bad so I just replaced it with the RS fender. The passenger fender was not RS so I had to weld tabs. Scroll down to see how I built my own tabs from scratch.

 

Since my passenger fender was not the RS fender, I had to make my own tabs from scratch to adapt to the RS headlamp Bucket housing.  The driver fender was brand new and already had the RS tabs on it.
