I`m pretty sure the Baja Club have one, but not sure how established a  member you need to be to borrow it - might be worth giving them a yell (facebook)

Mhmm, It suits me to leave it as it is to be honest and happy to take your recommendation, however how come weaker heavier & more complicated is considered a superior design?

  It was only a superior design in road handling,, The weak part can be overcome by fitting 100mm c/v's but the big one and is why VW stopped fitting irs was cost and like now you can pay more for a AM code IRS box and for a drum to drum swing-box AC box,, and do they class it as a chassis mod If the dvla! or mot!! take a look at it?

Swing axle system far superior to IRS.  (Note swing axle is also independent rear suspension).  You have very, very strong "axles" within the tubes on swing axle. Not so with irs. Swing axle is the preferred option for the offroad guys. See any us baja vehicle.   
In a nutshell... the irs was introduced in an effort to soften the ride at the rear and you could argue also to reduce negative camber. Mr porsche got his design right first time way back in 1936. Sadly production costs and also maintenance times\costs came into play. Front end king & link pin bullet proof not so ball joints. Yes I am a die hard fan of the swing axle - k&l systems.   ;-)up ;-)up

Thanks for your help guys, appreciated. I'll stick with the swing axle setup.

I think that's the only time I've seen someone recommend the swing axle for offroad over the semi-trailing arms.
 As for the US, I'd say apart from the regulation-restricted cars, 95% of their bajas, rails and buggies are on trailing arms, not swing axle.
One of them mucky ones. Sorry.

Ha ha Philip.. You have let the cat out of the bag.... You are a young guy .  ;-)up ;-)up   As you say modern technology has become the in thing over the pond. King and link pin + swing axle ruled in the buggies early days. It`s simple, it coped with the baja offroad races and it coped with the africa trip for james may.

I was presuming the OP was just after advice for a street legal buggy, not a serious off roader coming from Grenwich as he does  :-\

Maybe, but I'd certainly take issue with it being a far stronger design for off road use  - yes, it gives you stronger suspension arm, but it also pus all that force into the gearbox casing so for offroad use in the UK where you're likely in somone's big 4x4 tyre ruts, rather than US/African desert stuff, that generally means you're going to flex the gearbox casing every time a wheel shunts the side of a rut and if something big enough that it would trouble the IRS setup, then it's big enough that your swing axle is going to strip some gears.
