I made some good progress over the weekend, ticking off plenty from the massive 'to do' list.
I finally managed to get the b@stard nut off the old prop/diff connection (the one that took me 4 hours!) and did it without damaging the old prop (now for sale)
Old prop on left, 'new' on right - bearing & doughnut in excellent order
New prop fitted up a treat. Saddo in me then decided to clean up the heatshield - I've cleaned the thread of every bolt that's gone back on the car, so why not. Came up lovely:

Doesn't show the rear part as I cleaned that separately.
Mounted up the front half of the exhaust to the manifolds I have. I don't have a rear half, so let me know if you have one I can buy. No pics of the exhaust, sorry.
Next came a fresh drive belt (serpentine?). I couldn't believe how much the old one had stretched.

The radiator followed:

And fitted:

Then came the steering linkage, followed by some new ARB bushes - no pics.
Bought some other new goodies - Lemforder bottom arms & drop links, new oil filter etc:

As I'm replacing the whole front suspension with proper BMW Motorsport suspension, I've been replacing all of the bushes and ball joints. I also picked up some new Lemforder steering arms & track rod ends today, plus a spanking new Bosch battery.

Should be able to get some more time this week during the evenings and another session next weekend when I hope to be starting her up for the first time!
