The stock E28 535i bushings do not seem to last too long. The upgrade to 
install 750 bushings. They almost fit.

1) You can bend back the mounting tabs (a pain) and risk cracking them  
(E28 front subframe cracks, esp on steering gearbox are not unheard of) 
and trim OD down so they fit in the arms.

2) You can do it right. They must have their OD trimmed to fit in the 
arms. Then center of the bushing must be reduced to fit into the bracket. 
And the outside of the bushing length must be trimmed to allow for proper 
arm movement under hard driving. Failure to do so can consiveably lead to 
cracking and failure of the arm.

Steve D (www.ultimategarage.com) offers the properly trimmed bushings as 
does Dinan (www.dinanbmw.com and via www.bavauto.com). I assume others do 
too, but ask if all three machinings are done.
