Well that was quite a few versions ago so I'm struggling to remember!
I do recall buying a kit from the 'States, but it positioned the engine so high and forward that I ditched that.
It's just a case of juggling everything with the jack and chokking the engine into the position where you want it. Main consideration ends up being bell housing clearing the bulkhead and tunnel, and getting the ideal propshaft line - or as close as you can.
Get the engine mounts you want to use (think I used Torino ones on the 351w, but there's a few options at the likes of Real Steal to choose from) then work out what you want to fab up to make it work. As you might have seen, I went the way of ears coming off the cross member which worked pretty well.
If you need a rear hump sump to clear the Sierra crossmember (and steering rack) let me know as I've still got a Ford Racing one spare which might save you a few bob..
Cheers
