Doesn't the TR6 have a seperate body and chassis?  At any rate, BMIHT make
TR6 bodies and deliver them on a transportation 'chassis', presumably
Pressed Steel or whoever could have done, if not actually did, the same.

I do remember reading something about soft-die tooling somewhere in the MG
story, but wouldn't it have been a bit early for the MGB?  The special deal
I seem to remember was a higher unit price in return for lower start-up
costs.  It was the only way they could get enough funding I think.
