Hi Roger -
I took a quick look at the workshop manual. If I got the dimensions right, then the bridge is showing slightly high. The manual doesn't really show any measurements to the body mount plates on top of the cross-member. One thing - is that the body-mount plates show level in the manual, and mine are inclined which isn't right. The challenge here is that it may have to be adjusted multidimensionally. The top may have to be changed and then the overall height reduced. However, this may also change the angle of the mounting pins. It would be interesting to know what the distance be
