87 r10 350 exhaust manifold plug
« on: May 06, 2017, 07:25:52 PM »
Passenger side smog tube by number 2 cylinder. It was deleted by previous owner, but just cut and pinched closed. Seems to be 5/8 18 thread but can't find a plug for it. Any help is appreciated

I've seen guys use brass plumbing fittings from Home Depot and just cross-thread them in there somehow.
