Here are a few part numbers... can anyone say what they are?
 

I'm going over the engine invoice on the 2.7 Carrera. There are a couple of parts I'd like to get more specific info about.

Here's the numbers:
930 105 04900 Studs
911 100 90112 ??? Set
930 101 17000 Tensioner

I think I've tracked down the person who owned this car when the work was done. Maybe they'll be able to offer some info on the engine work.

930.105.049.00 -- 1976 revision of chain tensioner issued with first '76 Turbo ... not considered reliable, or a successful fix!

911.100.901.12 -- complete engine gasket set, 2.7 CIS

930.101.170.00 -- 1st generation Dilivar stud issued with '76 Turbo

Thanks Warren. At least I have some idea of what was done when this engine was rebuilt.
