"We've had a bugger (hermetic's word) of a time finding a drive shaft" LOLS! I had loads of those from Mk11 and S types, ran an S type 1966 as a road car for a couple of years, lovely car, with very forgiving handling! On one of my race cars I took out the drive shaft and coupled the gearbox direct to the differential with just a hardy spicer UJ, made up from the ones at either end of the driveshaft. and sat astride the gearbox with a remote shifter on the left hand side. Loads of power, but a bit of a handfull to drive..........................won races though. Later on I found out why it was a handfull to drive when watching some slow motion film of me racing. I had converted the steering on the Jag front end from steering box to rack and pinion, and as it bounced round a corner, you could see the front wheels toeing in and out as the suspension went up and down! Needless to say it was torn to peices that winter and rebuilt wider, lower, and with a double wishbone front end robbed from a Triumph Vitesse.
