My bro-in-law has an '88 Macro cab with a 2.6litre that has a scary exhaust manifold and is in dire need of new soft plugs in his block. Our local super-hero mechanic is afraid to breath on the manifold as he's been told they are not to be found. Is this true?

Just trying to help the lads out. I think they're eyeing the manifold on my '89 Ram50 with anticipation. Hell no, I go! Not giving Rambini up till they pry the key from my cold,dead fingers.

Any help will be appreciated. Thank you.
