[Fot] Spitfire driveline vibrations

[Norlin Engineering]

Friends:

Still having vibration issues with the driveshaft.  Showed up on the chassis
dyno and at the track.  I've had the rear wheels rebalanced, so it sort of
points to the driveline.  Starts around 6 grand in 4th and doesn't really
get worse with speed.

The driveline repair shop and I both feel it's in the slip joint.  I noticed
some radial play in the joint before removing the shaft from the car to take
it into the shop.  Once removed, it's almost undetectable.

The shop has not disassembled the slip joint yet, but they suspect that the
shaft was disassembled at one time and some of the rollers were left out
when it was reassembled.

Which brings me to my question.  I've searched the regular parts sites and
no one even mentions these rollers.  The factory manual from the '60's says
do not disassemble this part on pain of death - more or less.

Does any one have any of these rollers from an old shaft, or know where they
might be sourced?

Thanks all
