Find the exact center of the bore (VERY IMPORTANT). See here to learn how: https://youtu.be/VY2crpjhL3E

Keep track of how much you take off. Don't want to overshoot. Measure often.

Open and close the valve several times and it should self center and seat. Mark the hole locations in the plate.

Reinstall the plate, doing the 'open, close' routine a couple of times to center the plate.

It seems like there's a slightly bigger gap than stock, but I'll see how it idles and remake the plate if needed.

Lowes only had 6-32 x 3/8" brass screws. Still deciding on whether to keep these or order some 3/16" or 1/4" screws.

Seems slightly undersized, but I'll run it like this and see what the idle is like. If it is leaking too much air, I'll make a bigger plate

Lowes only had 6-32 x 3/8" brass screws, which means they protrude into the air stream. Still contemplating ordering some 3/16" screws...

So Felpro sells 3 different kinds of bulk gasket material - this one, a rubber-cellulose blend, and a rubber-cork sheet. I'm sure they make others, but this is what Advance had on hand.

Cut the gasket out and make adjustments so make it fit. It's important that the gasket isn't obstructing the 60mm opening, as you just went to the trouble of being able to use the entire diameter for airflow.

Poke your holes - don't have to be perfect, as long as you don't rip it and cause a path from the 60mm hole to the outside world.

To get the old one off, I got some vise grips on the nut super tight, then hit that brass fitting with my propane torch to expand it. After a few seconds of heat, the nut broke loose. (Cool how they stamped the manufacture date on the inner fender...)
