When you discuss a slightly longer wheelbase between 1800s and MK3 Grantura models are you referring to a pick up point / castor angle change within the original chassis dimensions? i wasn't aware that the chassis on the early thurner cars had changed apart from the adoption of tubular lower wishbones with the 1800S in place of triumph versions??

To clarify, I didn't mention a wheelbase change and I agree with your first paragraph.
I did refer to a slightly narrower
track for the earlier MKIII (1622cc) car and if you look at the data sheet I posted you will see the figures I was talking about. The eighth column shows identical basic dimensions, including wheelbase, but the thirteenth column indicates a slightly different track. I believe this data was culled from the original homologation papers for each model and I came by it many years ago amongst a pile of various TVR stuff.
Finally, my name is not Jim. But let's not get into the whole identity thing, there are other threads for that.
