If you were closer you would be welcome to borrow this. Maybe someone closer has one. Alan.

On my 4A I removed and replaced the J Type OD ( yes J Type ) without removing the GB. No problems. Alan.

Worst case could be the diff knocking. Alan.

Can't agree with that . From experience it works very well with solid 2k colour and can't see why it wouldn't work with clear coat. Here's one I prepared earlier

If you're going to flat out the orange peel suggest you apply a very light guide coat first. Alan.

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.
