No problem 340_duster,
Here you go..
Nappa part number N0E8131509 ----- 2- 1/4" diameter
Nappa part number N0E8151001 ---- 2" diameter
Nappa part number NOE8155008 ---- 2-1/2 " diameter.
I've listed them all in case anyone else reading has a different diameter they need. I've used these on my 1968 Barracuda restoration and they work perfectly, plus, they look as close to factory as anything else I've seen.
Hope this helps!!
