Ok so I was thinking of using motorbike shocks on the Spitfire but the rear has the leaf spring. Is there any reason I can't remove the coil spring and just run the shock on the rear?

Structural integrity of the upper mount. It would become a now now-overloaded upper shock mount.
The Spitfire upper mount is plenty strong enough (hint: transient shock loads far exceed spring loads) Lots of folks have gone to coilovers. ISTR that the Abomination used MC coilovers, and there have been a couple of threads on MC coilovers too.

But aren't you asking about removing the spring on the shock and just using it as a shock along with the leaf spring? That wouldn't be a coil over and I can't see how it could possibly make the shock mount loading any different, except for a change in the stiffness of the shock itself. Or am I misunderstanding the question?
isn't the transverse leaf spring on the spit MORE than just a spring? I thought it was also a locating member of the suspension
Yeah I thought the transverse spring was also an upper locating link on that car.
Yes, you can run just the shock.

Yup that is what I am asking. I am just getting an idiot check to make sure MC shocks don't have anything weird going on.
The motorbike shock is probably too soft to damp the much higher spring rate and greater mass of the spitfire hub and wheel adaquately. I would find a set of adjustable Koni NOS shocks and go from there.
The YZF-R1 shocks have to control a ~500lb/in spring. That should be plenty stiff, right?
Just to make sure and reconfirm I'm right, I checked the rear suspension on my 67 MkIII and it doesn't have a "coil over spring" on the shock. PRI makes a rear suspension kit that does away with the transverse leap spring and adds coil overs.
