You will have to either have the crankshaft machined to have the reverse
scroll (a backwards 'thread' on it to push any oil back into the sump)
removed and find a seal that will fit, or, more easily, get a later
crankshaft that does not have the reverse scroll on it and use that with the
rear housing and seal. IMHO the cast iron rear main seal does the job of
stopping oil coming out just fine, unless you park the car on a very steep
hill.

Did that on my Mk2, and found the handling to be a vast improvement. Having
said that, I did this before the re-introduction of the camber
compensators - and these do not need the front anti roll bar changing due to
the retention of rear roll stiffness, but they do reduce the ground
clearance below the diff. To block off the redundant centre mounts, I cut
the old studs down, cut a slot in them and screwed them in using a bit of
thread lock to prevent them moving again.

What, 7 spitfires? And four of them Mk1's? If you ever want to sell an early
one....
