Modifying the bracket went well, if a bit messier in the back:
Very tempting to get a nozzle with a pointed tip for the MIG welder, if such a thing exists.
It fits nicely, considering the accuracy needed to make sure the alternator's bolt lined up through the entire curve of the bracket. I installed spacers after mocking it up here:
However, I'm still not sure if this will work with the 1989 4-pulley setup. Again, have to wait for the Sanden to arrive before I can figure that out. If I deem it wise, I'll extend the BPE brackets to move the alternator mounting up and outwards away from the cylinder head.
In other news, the Magnum exhaust manifolds I bought had a bung for an air injection pipe on the passenger's side. While it was easy enough to buy a Steiger Performance blockoff plate for it, it was a pain to find the gasket, Mopar #53010000. It's available, but try to find it listed in any parts store catalog. It doesn't come up under EGR or exhaust parts.
However, one eBay seller thankfully cross-referenced the Mopar number, and apparently the gasket is best known as an EGR gasket on 2004-09 Nissan Quests with a 3.5L V6, Airtex part number 3F1078. Seller gave these alternate part numbers as well: 14719-4S100, VG179, 70-1150, EVG175, 3F1228, 779-2681, FE337, E879, 2-2580.
Not a great picture, but the gasket is installed:
I also found out that I bought the a 727 inspection plate instead of one for the 904. Anyone want to trade?
I re-installed the plug wires. Looks like a spaghetti factory, and I'm a bit ticked that cylinder #4's wire is too short (no matter what the wire combo) and the others are a bit too long. That, and they're that bright freakin' red - but I figure the used 7.5mm wires stand a slightly better chance of preventing crossfire than stock 7mm's.
I have, however, cooked up a great idea to route thee wires in a classic way, using the stamped Magnum covers. We'll see if it works.
And an overview shot, for the sake of it:
