A pair of 5mm thick heat insulator mounting plates with 4 gaskets to suit Weber DCOE or Dellorto DHLA 40 , 45 mm side draught carbs, this will help reduce heat transfer from the manifold to the carburettors and create a total seal .

This carburettor to inlet manifold mounting spacer system was used on many early BMW and Alfa Romeo cars using sidedraught carburettors instead of the more common rubber o ring and Thackery washer system . 

A very secure and excellent sealing solution .

2 x Phenolic spacer plates , 4 x gaskets .
