[TR] [Spits] Frame swap on Spitfire

[Joe Curry]

A little known fact is that from the first Mk1 Frame through the last 1500
and even including all of the GT6 frames they were all serial numbered
consecutively with the FC prefix.

That in itself tells you a lot about the interchangeability. But it does not
tell the whole story.  The later frames have rear extensions that were added
to comply with safety requirements.  In addition some other slight
differences (like cutouts in the right frame rail in the engine compartment
for exhaust clearance and several modifications to accommodate engine and
radiator mounts as well as rotoflex accommodations) were made throughout the
years.  But in general the frames should be interchangeable, especially from
one Spitfire to another.  

The one you are using is probably from an early (Mk1 through Mk3) Spit based
on your description of the rear spring.  

If it were me, I'd use the 6 leaf fixed spring because I so vehemently hate
that swing-spring KLUGE that Triumph used in the square tail models.  But
that's just me.

Cheers,
Joe

Subject: [Spits] Frame swap on Spitfire

Hi all, I have perforation rust in the rear frame rails of my 78  
Spitfire. Am stripping an older frame (unknown year but has 6 leaf  
rear spring) for bead blasting and POR-15 painting.
Can anyone confirm my belief that all Spitfire frames are  
interchangeable?
I understand that the 12 coil front spring from this frame might be  
advisable for lowering the front end and improving handling as opposed  
to the 11 coil used on the 1500.
I will of course use the swing spring from my 78 along with  a Monroe  
air lift shock kit at the rear.
Any insight into what might be wrong with this plan is welcome.

TIA,
Robert Rutherford in Vernon, BC
