I got one from London TR Shop. Fitted no problem. Alan.

I had similar. When they got dried out the coating curled up and rubbed on the disc's resulting in squeaking noise. Not recommended. Alan.

TR Parts Catalogue shows both but no fitted from info. Alan.

Snap, well nearly. Alan.

At the TRGB engine rebuild seminar anything between .003"/.010" was stated as being satisfactory. Not as critical as was commonly believed. Alan.

I got the bracket kit from the TRShop. Been on for some five years now with no problems. Alan.

My 4A had the same problem. Had it serviced/recalibrated by JDO Instruments. Had to take a number of measurements for calibration. Detail is on their website. Speedo is now reading spot on against sat nav. Alan.

Try Revington. I got one there a few years ago. Alan.

I used a sand bag between the diff and trolley jack. Worked fine. Alan.

There is normally a discount for collection of orders at the NEC. Alan.

Looks like the thread pitch is not the same. This would cause the bulb to tighten the further it was screwed in. Alan.

H Roger, Did the diff rebuilder comment on what if anything as wrong with your diff? Alan.

Have a word with your paint supplier. Mine had some "under the counter stuff". Don't know what it was but it worked a treat. And I'm still standing . Alan.

I removed and replaced the J type on my 4A without removing the GB with no problem but would imagine, as Pete says, if it's a A type putting it back would be very difficult. Alan.

The follower could have come part way out and now be angled over preventing it dropping down into position. Try using a magnet to pull it up and centralising it. Alan.
