Despite being back to square one, I did find the problem.

The machining wasn't consistent ........



I know that pics can play tricks on your eyes, but it looks like the center hole is counterboared off center or the 5 flywheel holes are off center? It looks like some of the flywheel holes are cut into by the center counterboar hole and some are not? If they were all centered, all of the flywhel holes would have the same amount of intrusion from the center hole.
Sorry if I see it wrong.

Thanks for the feedback and ideas guys.

Regarding the questions:

The 8 Caddy crank holes in the flywheel are not threaded - my son was liberal with the loctite but I've since cleaned the holes out.
The threads in the crank are fine, the bolt was spray painted with metalflake paint and the flash is misleading.
The bolt length problem was solved using 5/16" washers I modified in a drill press to fit perfectly.
Prior to making the washers (to see how thick I needed), I tested the bolt for bottoming.
During the last cap screw rotation the low ones pushed the crank endplay outward (you can see the rear main seal move slightly).
The 5 holes (that are not used) are not perfect in the making of the adapter but the crank flange to ring gear distance is true.

The washer solution worked well and all threads are still used through the crank flange - here are the pictures in chronological order:












Flywheel bolted up well and bolts clearly not as countersunk as before.


I rotated flywheel 360 degrees to ensure rotates freely and true given there is little clearance:


New issue is that I haven't been able to align the starter!
This flywheel has a new replaceable ring gear while the old flywheel teeth were quite worn.


Clutch, pressure plate, transaxle and slave cylinder back in:

Andrew and I were back at it this afternoon with the goal of installing the axles and reassembly of the rear suspension.

First my son installs a grease gasket on the flange:


They are supposed to be self adhesive but they stick to the CV joint better due to grease in the area:


Then it's just a matter of torquing the 6 cap screws:


Checked to ensure the axles rotate smoothly throughout the entire suspension travel:


Next handbrake cable is reattached along with coilover shock, UCA ball joint and axle nut:


Once the wheel was on, time to repeat everything on the driver's side:

Last night I found the old starter and thought I might have better luck aligning it with the new flywheel:


It's kind of the reverse design of the newer starter so the wire connections will go on the underside once flipped over:


Unfortunately once installed, it also didn't mesh properly - but since this one came with a shim, I tried it and success

Long overdue to post updates...found my curb weight card from the 30th so best to post it here in case I misplace it again

Thanks Danyel, Cheers!

Unfortunately, my project to change the final drive ratio in one of the transaxles didn't work out.
The plan was to have one transaxle setup for highway cruising at low revs and leave the other stock for best acceleration.
The ring and pinion I bought on eBay thought to be from a Porsche Sportmatic had a smaller diameter ring gear that wouldn't fit the differential.

Here's an interesting convertible I saw this summer while visiting Wiarton, ON on business.
They have a local cruise night weekly down at the waterfront:



The owner showed me the soft top which consists of two fiberglass T-tops and vinyl from the rollbar to the firewall.
It also had the soft sail panels that snapped into place near the engine vents as part of the design.
