That is an old picture when it was mounted on my 2.5NA. The mounting is identical for a 200TDI and I simply unbolted from that engine and bolted to the 200TDI.
I've attached a closeup of the bracket. I can take pictures tonight on the 200TDI, if you need. The compressor is a York long stroke. 15 seconds to air a tire!!
Anyway, a quick description. The bottom plate is 1/4" or 3/16" with holes for the stock A/C mounting points. A 1/2"? pipe welded to it as the hinge and a tab for the adjuster arm. A couple of pieces of angle drilled and bolted to the compressor with a 1/2" bolt as a hinge pin. Another piece of plate for an adjuster arm.
Drive is via the stock crankshaft A/C pulley. If you don't have the pulley, they are $25 new or something like that for the 3 groove.
