egr blockoff plate

[snowboardman137]

hey guys, putting headers on and need to eliminate my egr, does anyone know what the part number to the blockoff plate tin piece on the intake is?

GM part no is... 12558346

Or you can use a rubber freeze plug that expands when you turn the nut. Can't remember the size, but it's just over 1", maybe 1 1/8th or something like that.

I have used a freeze plug and was not happy with how it looked and fit. Got the gm part at the local dealer for $9.
