AC-compressor differences

[Dag Bøsterud]

I have a 1990 Audi 100 TQ Sport Exkl. with the 10P17C AC-compressor. The compressor has the two-piece design manifold.

I'm thinking of buying a new (rebuilt) compressor, and some shops offer the compressor without the manifold, whereas
some shops offer the compressor with the one-piece design manifold as found on the Audi 100 with four cylinder engine and
Audi 90 etc etc.

I've also read that the two-piece design manifold is a bad design, prone to leakage. Currently I know that mine is leaking between
compressor and manifold, but there was no way of telling if there was a leakage in the manifold itself.

Will a one-piece design manifold fit my car? If not, what will have to be modified?
