[TR] [Spits] Frame swap on Spitfire

[Joe Curry]

Right on target Bill.  I forgot about the hinge points in my post.  Those
are the most obvious differences in Spitfire frames and very likely are
different on the one he is planning to use.  But if that part is ok from the
frame he is replacing, he can certainly cut that off and weld onto the donor
frame.

Not strictly true. While the basic frame is the same, the front bar and
bonnet pivot points were substantially different on the roundtail cars, ie
all those cars with the fixed rear spring. The frames can be converted, but
why bother when later frames are readily available? There were also detail
changes to the frame where the wider exhaust twin downpipe of the 1500
passes.
Additionally, late US cars had frame extensions for additional crash
protection under the boot (trunk) floor. These were never fitted to home
market cars, they are not a structural necessity - it's your call whether
their absence bothers you, 
Cheers, 
Bill.
