where am I going wrong?

OK thanks AJ all good info, so first of all the bell housing we are using us not the ball style but rather the pointer style so it goes into a little window in the bell rather than on the ball I'm sure you know what I mean but it seems correct as it moves freely and is centered in the bell window the Z bar is 90 degree to the block but it is a bit higher on the engine side than the frame side and our motor mounts are as low as they can go in the bracket for the mount we are using the biscuit style mount maybe you have a picture of how you mounts are if you using they same style? That being said I think the over spring is a big part og my problem but haven't removed it yet it's tough to remove but hoping to use the screw trick previously mentioned above this weekend thanks.
Yes, there are at least 2 different height blade style pivots, if You have the short one it may not be a match for Your combo. That can run You out of adjustment easily, there
are a couple of different length adj links as well, if You've mix & matched stuff that's probably what's up.
