Neither 2wd/4wd/escos/ or scorpio fit with the "solid/poly" diff mounts.
I have a scorpio sallon roll bar, nothing like going to fit.
I have just ordered some sound deadening pads to quieten a bit of noise.
I have a man making me a one off roll bar from EN16T proper correct sprung steel, in any thickness I like, was going for 22mm, but will think very hard about a smaller diametre now as roll is reduced significantly with new diff mount.
The scorpio roll bar is actually slightly closer to the mount than the std roll bar, although will fit with std mount no problem.
The solid/poly mounts are very bulky, and whereas the std mount goes OVER the lugs on the diff casing so it so further away from roll bar, the solid/poly ones sit flush on the lugs on diff, and are about 1 1/2" to 1 3/4" thicker on the diff casing.
In light of not being able to fit a roll bar on would I do it again ?, without a doubt YES, just too many advantages, I even forget most of the time it is not running a rear arb, that is how good it is, I don't think I am going to try the front solid mounts that I have, as the amazing difference shows just how bad they were to start with, my std diff mount was a new one, and was also packed with poly bar to make it stiffer, but still no comparison.
