As I was saying below... I have the part numbers at home for what you need. I'll post later on when I'm off work.
Regarding the rivets...I don't think they are necessary. I brought this discuss up recently...

Since then I have found a better solution. There is a small black fastener that is only found in a handful of places on the whole truck. One is just about the driver's head area. The interior side panel, up at the very top, and to the very front there is a black cap that covers a hole. Inside the hole is a small black fastener. This fits the rivet holes perfectly.
When you fasten the cladding pieces in the tire well areas, I also replaced the body bolts AND the threaded pieces they go into (don't know what they are called).
Now that all grommets, body bolts, fasteners, etc. are new I tried replacing all cladding pieces (without using tape obviously) and everything is tight and perfect. I don't think the rivets are needed and instead I will just use these black fasteners. I'll post that part number later as well.
By the way, I have about a dozen of the rivets that I got from Merlin for sale if anyone is interested.
