Mukuni carb intake flange spacer

[yippi427]

I need some help finding this intake flange spacer between my Mukuni ph44 carb and intake manifold.

I purchased my Datsun 240z with the triple Mukuni carbs already installed. I'm trying to purchase new spacer due to cracking and the only number on the spacer is #86974. Want to replace all 6 spacer.

Any information where I can some replacement part.

Thank you for any suggestions.

I spoken to Dave at dave@tuning4performance.com

Dave helped me with what I needed for my Mikuni carbs

He is a Mikuni dealer and very knowledgeable with many years of experience.

He helped me with the tuning of my Mikuni 44 Phh after speaking with Dave he set me up with the correct jets I needed.

Dave also provided the solutions for the issues with my Mikuni carb insulators.

What were your solutions?

When inspecting the carb insulators I saw small cracking on the insulators but fuel is not leaking and the 240z runs fine. So I was thought it is better replace the insulators with new ones. After speaking with Dave he said the cracking is cause by age of the rubber material and suggest removing the insulators and inspect the inside for any cracking. If the inside of the insulators looks good he suggested cleaning and spraying the outside surface with multi-purpose rubber coating ( Performix Plastic Dip) which will seal the cracking and make the insulators look new. He has done this before and help owners to save having  to buy new discontinued insulators which sell for $100 ea.

Insulators might make another good offering?
