Spacer for universal holder

[smokey@alaska.net]

1- Your location: Alaska
2- Receiver make and model: Viewsat 7000
3- Dish size:36"
4- LNBF typeigital Pro Model #151018-NS
5- Motor if any:N/A
6- Now to your question:I am looking for a spacer so it holds my LNB in place in a universal holder. My LNB neck is small than the holder. There are spacers that you csn put inside to hold the neck in place. I was wondering if you sold them seperate from the universal holders?

Thank you for your help.
