4 weld center caps and shock plate

I've got 4 new WELD aluminum center caps I will sell you, but there are different O.D.s listed for them. The one's I bought from Summit Racing were as close to the size I needed as I could get but are just a tad too small & don't center in my wheels.
I was going to use them on my A.R.E. wheels on my Dakota. (don't really like the factory one's on it now)
Summit has them at around $20 each + shipping.
I can get you pics & I.D. measurements but I want $90 for all 4 shipped.
