There is very little movement with race/offshore mounts. You can tweak it a very very little bit if needed by loosening the bolts, but usually it does not get out of alignment either. If its way off for some reason, then the mounts need to be redrilled. I would also be looking for a reason as why the alignment is off.

already replaced the u-joints , they were falling apart. Ha !
Thanks for all the replies. Will keep updated.

ive seen couplers come loose and also flywheels come loose, u might want to retorque

Saftey wire the exhaust flappers closed and they'll stop making noise.
