Thanks for the replies - it's a good start. I should mention that I'm in the process of some changes & the truck will soon have 5 bolt pattern wheels. I mention this as I know (if I find one) I will have to change the bolt pattern from the 8 bolt.

This pic (not my truck - photo from Ebay)is the way I see this mounted:
