I am installing the front fender extensions on my Super 88. I purchased the clips from Fusick. My problem is the holes in the front fender area are much larger than the post on the back of the clip that it is supposed to go into. The rear post on the clip looks threaded, is there some sort of fastener that goes on the post to hold it in place? The fender extensions came in a parts box with the car, so I have no reference to help out. Any info would be greatly appreciated, Thanks
