Strange timing bracket. Application?

He said it's going in a pile. :D
Yep. Unless I can make this work... pre-68 tabs are hard to find, but big block bolt-on tabs are cheap and available. I'm gonna buy one, cut the bracket off, and weld the timing part to my bracket. I think the balancers are the same diameter. If it doesn't work, I'm only out 10-15 bucks.
