Carefully screw in the pilot bolt about a turn or 2 until it feels loose. with your finger on the nut, unscrew the pilot bolt and set aside. Run a 10-32 bolt with a large washer into the tee nut and tighten until it pulls up tight to the back of the firewall.

Check with an inspection mirror to make sure the tee nut is pulled in fully. Final check of the fit and you’re done except for working out the throttle pushrod location. I will give the plate a couple coats of polyurethane. Note the use of button head screws. I found that there was a slight interference between the bottom 2 bolts and the muffler. The button head screws cures that.
