Hello. I had some of these made for my cars.
Have 2 sets of 4 spare for $30 posted per set. Suit Silvertop ITBS.
Punched and nibbled by cnc then hand cut from the sheet.
Good for those ITB conversion builds where you used Silvertop ITBs on a custom manifold and have not been able to retain the stock 20v Bakelite Insulator manifold gasket.
Could also use them on a stock Silvertop I guess, but the effect would not be as significant.
Not something I'm making again, just offloading the spares.
