What is the part # for engine Manifold bolts/studs ?

There are 4 studs to connect the engine to exhaust manifold. the 4 on my engine rust so bad that its not re-usable.

Been looking thru the FSM for so long, but just cant find the part number.

THis is for S5 91 NA engine.

Anybody know ?

Thanks !

The studs are M10. The intake manifold bolts are all M8.

Hit up your local fastener store. All the stuff you need should be less then $1.

In parts fiche, engine section, housing sub-section:

D-Code 10 105A, part number 0839-10-105

Same for NA and Turbo.

From an 86-88 Parts fiche, but the 89-91 should be the same for that part.

I did a search, and found that its M10.

I just came back from Home depot and 2 hardware stores. "strangely" NONE of them have them in stock.

Am I out of luck or some **** ?

You need to go to a fastener store, not a hardware store. Yellow Pages -> Fasteners.

I bet there's at least one in New York.
