This is because the case started out from the VW foundry as a bus case with 
all the mounting bosses in place that BOTH a bus and a type3 used.  The case 
was then machined specifically for a type3 afterward. If you look at a universal 
case, they have the same casting numbers too, as they can be used in a type1, 
2, or 3.

These are just casting numbers that are used by the factory to tell what time 
and day it was cast. It is more of a control number for VW than anything. I 
have some around here that have an 86 on them, and they are single port heads.

I think your missing the above info, you probably have an original type3 
engine for your car. The way to really tell is the number/letter codethat is 
located next to the part line of the case halfs, and check Dave Halls site to see 
if it was built before April of 73, as the engine would normally be built 
before the car was sold if it was OE.

I don't know what this numer corresponds to, it might have been a warranty 
replacement engine while the car was still under warranty. Russ??
