Need EGR plugs for M1 Intake P4510016
Woohoo! Just got lucky and picked up good used M1 intake manifold P4510016 off my local craigslist that I plan to use with my upcoming 408 build. It came with the bulk of the install kit hard parts, but not the EGR plugs. There are 2 spots I'd like to plug - the very rear of the intake, where the EGR tube attaches and along the cast portion of the EGR tube as it makes its way to the intake plenum. Does anyone know right off what the thread size is of these holes, so I can find a plug for them?
