Bill,
90w was specified by MG, circa 1950. Most today use a multigrade,
80-140 is one I believe to be pretty common. Others think highly of
synthetic oils. I have never seen anyone write of differential
troubles that could be attributed to oils other than 90w.
> 1. What weight of gear oil is recommended for the differential on
TD's?
The radiator shops around here spray Rustoleum semi gloss black on
rebuilt rads. It's now labelled as 'wrought iron finish' or something
not quite 'semi-gloss'.
> 2. What paint do you recommend for dressing up a used radiator

The best explanation I have seen is by Chip Olds, in his tech articles
years ago in The Sacred Octagon, reprinted in the T-Series Manual. I
recommend that you add this book to your library for it has dozens of
experienced-based helpful ideas.
Chip said that Nuffield bought, at end of the World War (I) a French
bolt factory set up in England. Production was continued with the metric
sizes then used of threads, but bolt heads and nuts were made to fit
English wrenches, Whitworth/British Standard sizes. These hybrid
fastenings were used on engine & gearbox. (when you remove a fastener,
stick it back in the same hole)
The rest of the car used BS/Whitworth fastenings, except...another
exception.... the rear axle and wheel nuts came to be "unified" as in
unified with USA sizes, about car number 14000. If you see a little
ground-away bit in the center of the corner of the flats of the wheel
nut, it's Unified. Unified takes US wrenches and has US thread.
WHile it's possible to disassemble and reassemble a TD with a
collection of metric and US wrenches, that's the hard way to do it. Buy
yourself a set of WW/BS combinations and sockets. Using something that
doesn't fit right will end up with buggered fastenings and damaged hands.
