Update, after a very long time! (E's not quite dead - e's getting better!)
The engine is finally out.


The funny thing is how I thought I'd already ordered all the parts needed before I took the engine over to the engine shop for rebuilding and machining, but... no. Going though the list, I discovered I didn't have any replacement cam bearing. So back in December, I put an order into VP for a set of ACL cam bearings, then VP tells me they're out of stock, and ETA for new stock is.... four months. Sheesh.
Luckily, Planetman from TurboBricks had a line on ones that could be had sooner, and they've arrived.
I've decided to put one of the three ex-US M410s behind the B20B. The problem was how I didn't have any spare extension shifter lids for these boxes, and I was unable to source any locally. I now have two, but one of them has a chewed out brass bush in the southern end of the cover. Mother Volvo has a replacement brass bush for the front one, but not the rear (southern) one.....
Here's a pic of the inside of the good cover. You can see how somebody has made a long custom brass bush to sit at the gear lever end. The only spare part available off the shelf is for the one at the northern end, up near the gear selector gate; it's barely visible in the pic (it's near the hourglass-shaped thing which triggers the reverse light switch).

My Skandix order came in (which included 2 of the northern end bushes and their associated o-ring seals) since I also needed a replacement viscous clutch for the fan. Unfortunately, I ran into the same problems as sksmith on TurboBricks discovered with the fan clutch he'd ordered.

There's lumps of metal (tabs) near the mounting holes which don't allow the fan to sit on the clutch assembly.
I wonder if it's worth just filing these protrusions to get clearance, but as he pointed out, doing so might throw the whole unit out of balance.
And, despite the best laid plans of mice and men, I still have more parts to order. Damn. I did want to have this car running before Easter, but I still have to find someone to dismantle and overhaul the M410 and overdrive before installation. Ah well.
