A few misc. follow up items....
(1) Karl mentioned earlier an ITB 914 owned by Blake Meredith (aka bam914). He just posted a video of him in his 914 at Road Atlanta...

Nice sound from a nearly 40 year old pushrod 4-cylinder VW engine! Granted, it's had some modern high tech work done to it.
(2) I visited Wilders Nuts and Bolts a few weeks back to look for M7 or M9 cap head screws. They have nearly zero M7 or M9 hardware (no suprise). When splitting a caliper, I ended up trashing one of the special M9 bolt and nut. Luckily I was able to source a replacement from someone (from another caliper) as new parts are unavailable anywhere.
(3) Here are some photos of my split caliper and zirk fitting...
