    Clubman set will fit no problems, HD set will require some minor fettling of the housing to fit. (I assume it is the Quaife set you are talking about)

    Cheers

    Yes

    I have one of these in my green car and the housing and all other bits are just regular Ford single rail.

    Great box in a competition car but is a pain in the clacker on the road with its ratios.

    If you are trying to fit Quaife H/D gear kit you will need to modify the ends where the layshaft sits in the box. I had one done years ago and still not assembled the RS1800 gears. I was lucky and used the RS1800 case for Quaife kit and everything just slotted in.

    Roj,

    Like Ari says, I have an HD set and the standard housing had to be relieved to get it to fit. I can show you when I get back one of these days. I will probably end up selling the box as I've almost got the ZF parts together.

    I seem to remember JJ had a Tran-X set when I was down there about 10+ years ago, maybe your right. The clubman fits no probs though.

    Cheers

    I can supply tranX gear sets cheaper than Quaife.

    I have a straight cut rocket box in mine and I love it, but some days I wish I could keep it in 4th gear Too darn noisy.

    $1175 + local freight to you for the regular gear set (which are rated to 190hp & 7,500RPM)
    That includes the bearings.
    Any ratio you want from the 2.48 up to the 2.32 and various intermediate ratios.
    Assuming they are in stock, delivery in around 2 weeks

    the tran-x sets are great! i got a set off smcka and have done a few events with it and there great!.. another bonus is when you get a gearset off them they come with a bearing and gasket set as well to reco the box at the same time.. only mods i did to the box was tap the bottom of the casing and put a filler plug from another housing i had so now i can drop the oil out and keep it clean highly regarded! i just got a tran-x lsd installed in my rally car over the weekend and cam say only good things about that as well!
