Casting #s Questions

I have two distributors and two intake manifolds that came with my 65 GS. Can anyone tell me the casting #s for those two items that would have been used for the 65 GS?

Thanks - Cheryl

 

is one of the intakes a 1363782?

Cheryl - Here is a link (hope it works) that lists the intake casting #s:

My '65 intake shows a casting number of 363782.
A '66 intake is 37554968.

Is there a casting number on the distributor? I do see a 3-digit number cast in.
There is an alum strip wrapped sround the shaft with the number 1111055. That number is correct for several years.
