Never normally use these, but fitting JAG IRS into a Capri at the mo, and to get it in without the front "ears" getting extremely low and vulnerable to heavy knocks, I have fitted it a little "nose up".

The input is via a GAF type rubber donut, like those used on the big BMW's and Vauxhall Omegas.

The misalignment angle looks like being approx 2 degrees, depending on the final fitted height of the gearbox.....

Does that sound ok for a running angle, or too much....

Part of me says should be fine as plenty of cars in the past used these on moving driveshafts, other part says ooh thats a bit angled!!.............
