Opps – I had a typo in my post above I meant to say B6S for the J6 and J8s – I’ll go an edit that now! I use B6S.
Thx Mumbles for catching that. Only that (PU) number was B6Y at the cross reference I looked at. I have no idea what the PU means. If anyone wants to see where this came from go to the link below and scroll down to page 19.
