Stampede Chassis Conversion Questions

[TexasSP]

One frustrating thing is that the kit says it comes with everything.

Everything that is except the rod ends. My question is which ones do I need to use? The maxx ones have an inner diameter that is too large so I was thinking These would be the correct match.

Also, with the arm part of the kit there are to pieces of aluminum about 3/4 to 1" long and 1/8" wide with a hole at each end that I can't quite figure out what to do with. Any help is appreciated, maybe I am just blind to the obvious but it has me confused.
