The top cover on this ZF has a vent that has a 3 inch long tube that sticks down in the trans near the ring and pinion. If i mount the cover so that the vent is closest to the front then the vent tube clears everything inside but the two trans mount holes are approx 2 inches toward the back to far. If i turn the cover around and have the vent toward back--the trans mounts correct but the 3 inch long vent tube pipe hits the ring gear!!! wt-heck. The guy that took this apart is not around anylonger and i have never worked on a GT 40 SPF MK II before. I know these are the right parts--there the only parts-what am i missing here?
