I have a 1989 300TE with the m103 engine in it and need help on locating the exhaust manifold bolts, studs, and washers as well as the bolt of the intake manifold. I am not paying the price that the stealership is asking.

if no one knows of anyone that sells them off hand I was hoping I could at least get the sizes for the exhaust studs and the intake manifold bolt.

any help would be appreciated.
