Carolo - NAPA is a large franchise chain of stores here in the US.

I went to a local NAPA...it's a special order which means 2 days wait. I told them to overnight, which they did.

Now what you have to do is call a local store, get it, then ask if they can send it to you in the UK. You'll have to prepay with credit card, I assume.

You can find a store on their web, but no online ordering..the one I used in FL is 954-983-3150.

If it does not work out for you, let me know. If you have pay-pal or prepay with a check to me I'll order it and ship it DHL/FED-Ex to you.

PM me if you need help.
