Paul,
Many Spitfire and GT6 components were used on other models ie Toledo, Herald, 2000. Do you want to have another page for things like a DG gearbox or an FD diff.? I think I can remember it all.

Considering the diversification that exists in the variations of rebuilds... it might not be a bad idea to list any and every S# that might possibly fit in situ.

If you can/could, sure. Jot it down...and I'll tack it on the page. And of course...with proper credits where due   :-)
