Call out to sbc converted teener owners, Harmonic balancer and timing marks Options

[HalfMoon]

Owning a Renegade converted sbc 914, I've often wondered how other owners have solved the problem of not being able to see the timing marks on the harmonic balancer.
What was/is your solution (other than timing by ear)?
Thanks!

I got a tip from here to mark TDC on the flywheel as viewed from the inspection area on top of the trans. Have yet to fire it up and test it but sounded like a good idea. Should be enough space from engine deck lid area to shine timing light and use remote camera to check it. I asssume a timing light with an advance function is necessary since I won’t have degree marks on the case (just location of TDC).

Scott with Renegade suggested the same but I found (on my 73) that the wall comes right exactly over the top transaxle hole.
Opening a panel didn't allow the ability to see the flywheel and it can't be seen from above (behind the dizz) even with the rear rubber shelf removed....so that solution (at least on the 73 where the body in the trunk is slightly different than earlier models) isn't going to work.
The only other thing I could see for using the flywheel as a timing mark is to remove the entire trunk wall and install a shock brace. More work than I'd like for this particular problem.
I've decided to remove the inner metal front shelf (that is apparently only for holding the forward rubber "shelf") behind the access panel I created in the cockpit which should give access to the harmonic balancer. It'll take two people to time the car with this fix, but at least precision timing will be able to occur (I'm re-curving my dizzy, so timing marks are pretty important)
