I got a set from him of eBlag for about that price and they are new. Can't see him on there anymore.
There's an outfit ding them at fifty quid.

Basically as the title.
I've got a 3.9 with a ZF auto box. The borg warner transfer box has a hole in it. I have a good LT230T Transfer box. I think it can be fitted but what parts if any do I need to change?
