Hi Joe, pretty sure I have a pair which I put aside for a spare engine, happy to let you have the loan of them. I will double check in the morning, perhaps you could PM me and I will respond direct.
V6 2.8i. Like this maybe? Although there are 2 clips on the left side and 3 on the right side so they can't all be 4 slot. So maybe buy 5 4-slot clips and cut them down?
