Not a bad idea Nigel. I think I would change the Diff Bearings and seals, Clutch arm bush, Main shaft output seals behind Clutch release bearing and of course an oil change and quick inspection with the end plate removed on the main box. Note the bolts for the cover plate respect plenty of release agent maybe heat to prevent snapping. I replace mine with Stainless bolts as they carry no significant load. With the box in service if 1st to 2nd Syncro is OK then a second oil change with the box hot soon after using it to get the crud washed out. Beware the box with golden oil on top and black sludge below. This is oil breakdown and it etches the Syncros and trashes all the bearings. I saw this on a 24k only Monte Box that then needed all new internals.

Hi Carl

No problem, hope it fits the early car? Looking forward to your next installment!

Hi Eric/Nigel

Good call on the diff bearings, I have a new set of seals already. I do intend to drain the oil and see if there is any residual sludge. The first box I bought was supposed to be refurbished, but not by the seller, so it will be suck it and see time.

Thanks for the comments

Also just received a pair of new door keys from John Richard. He managed to source some new/old stock blanks with plastic ends rather than the solid metal ones. Fortunately the code on the end of the glovebox lock is the correct one for the rest of the car. The only key I had before this was an after market and had no markings.

You added some very good points Eric. I was perhaps
a little brief on my post!
Those diff bearings are easy to get and easy to fit, and don't
affect any existing pre-load set-up, provided the shims all
stay in place.
