Drive alignment on extension box?
 

Does anyone have or has seen a drive alignment tool for a Stellings 12" box?

We made one out of two pc of sliding tubing with welded plates that had the same bolt pattern as the the drive shaft. We set the angle of the solid motor mounts so the drive shaft angle was about 1 degree.

Forgot to say that we did all the X-dimension, pop testing, etc prior to the final repositioning the motor mounts.

had to make one for my IMCO boxes, find a lathe and start cutting.

just call IMCO , they have one that should fit or require minimal
modification ...

You could try the ITS alignment tool. It works with both the ITS and standard Bravo's because it uses a 2 piece slide and I think it might slip in far enough to work for the extra length. The 2 piece works well too because you can leave out the piece that goes into the gimbal bearing and you can see which direction the engine needs to move to center the bar in the gimbal bearing.

Thanks for the input.
