YJ ones are out of production - might find a used one.
This is true and if they were for sale a Safari would be about £285 apparently 
 
 I fitted a YJ one to my previous CJ7 and it worked fine obviously I had to make it fit. 
Looks like It could be a case of making one. Oh well of to B&Q then :? Not.
I have a bit of a fabrication shop so It looks like I will need some thin bore stainless steel pipe a few elbows and get welding.
