F-798 shim material

These are the shims that go between the fwd h/s spar and the aft deck. The print has you make these out of .125 ab4 bar stock.

I’ve looked high and low in my shop and can’t find any bar stock. I suspect that I was supposed to make these from the leftover ends of the aft wing spar carry though, which probably got swept into the scrap pile about a year ago.

Does anybody know what alloy and heat treat this stuff is and why I couldn’t just make it out if any old piece of .125?

If nobody has an answer of the top of their head I’ll call vans tomorrow

Vans includes pieces for various uses.
Ask a builder friend for some.
If no one is close, I'm sure I have some.
