Kevin they're as cheap as chips, Rex Ward has them. Its not worth the bother NOT too.

My experience has been that they are vital.

I misplaced one, and the advice I recieved was that they MUST be fitted.

So i ordered another one.

I also used " Loctite Extra Copper Silicon" high temp orange exhaust
manifold paste and have had no leaks 7 years later.

regards tony

Many thanks guys , have fitted new locating ring and used high temp gasket sealant ,, she runs sweet and on song now .. did have leaky inlet and drawing in to much air . she did not like that . many thanks once more
