Yeah,,, talk with Craig Williams at Jazz Wheels in Adelaide,,, he has one in his red/black mini sprint
Peter Thompson in Towoomba has one on his sports sedan mini, he runs a power tool shop up there
& 2 brothers Anthony & i`ve forgotten the other brothers name, from the gold coast had one in his mini (they bought it from Steve Winters...but i`m pretty sure they sold it onto someone else since then but don`t know who it was , but that one is still around)
Steve Winters took on the Aust distributorship years ago after my dad knocked it back & i`m sure he still has at least one head left, he`s the guy who had a cream lift/hatch back mini uo here in Qld for years
sorry but i don`t know where all those people are now tho
But i`m sure that Craig Williams can tell you all you need to know,,, he`s had his running for years (well ok with a few crashes & full rebuilds & sent back to England for repairs a couple of times

)
& Yes Tony from minisport in Adelaide also had one & he told me recently that he was setting one up & was going to be fitting it into a customers mini for a while,,, not sure of the exact details but i think it was only on a loan basis
Dam i`m just full of Twin cam info lately hey?
