ACC Rebuild Shop - Who was it?

I did a search and I can't find it, I'm looking for the shop that rebuilds the ACC push button control unit. If I remember right you send them your unit and they send you a rebuilt one.

I know I have been to their website but I can't find it.

Thanks

No, I have a friend that used them for repairing cruise controls, and they are tops in that category.
