Hi Simon,
Thanks for the offer of the GTD rear end. The V6 will remain in & as I understand it the upgraded rear end was because the type A I have is not man enough for a V8. In years to come I may change it to the "real thing" & cut the back end off but this is way off as I want to finish the car in its current engine / gearbox configuration (as its already done & seems a waste of money). Having run the V6 as it is the sound is fine & whilst it may be left behind off the lights but you 5.0 boys I'll make up for it on late breaking!
The GTS 40
GTs-40 as I understand (& from what I saw) was not finished but the chassis, bodywork, etc was. GTS are to also start to supply other parts (seats etc) so if you, or others, have interest I suggest you contact them directly.
