Safari Y60 Body mounts

[slmd32]

Well the body mounts on my y60 safari are had it (10mm ish free play when I get under there with a pry bar, no wonder it makes a good knock).

Nissan want silly money, ebay etc isnt much cheaper.
Has any one had any experience with doing any thing else here?
Was thinking of buying some urethane and machining up some up, has anyone done this before or found any other rubber blocks that work?
Are there any body lift kits that replace the mounts rather than space them up?
