Anyone modified Trans xmember to lower the Transmission ?

I thought perhaps I had the wrong height mount and purchased a correct factory style replacement. It was taller than the schuamacher mount I have .

Schumacher says that some 904 cases ( truck or rv) are slightly taller in this area. Unfortunately I do not know what my 904 came out of.. It's not the original one for the car.

Crossmember was the one that came with the car( slant six 904)

Will post some pics tonight..
