I'm having trouble getting the RB sway to fit through the stay rod (strut rod?) mount. I can't get it to fit through the hole. Is this normal? Should I just cut the hole or beat the mount with a mallet until it goes through?

 

Yes, you'll need to make the hole a bit wider and open it up at the top to keep the bar from rubbing against the bracket once you tighten it down. I also needed to clearance out the frame rail seams on my car.

Its quick work with a dynafile if you can get a hold of one.

 

^What he said, a few mins with a file or die grinder etc and it'll fit fine.
