yea the rear lower lca for civics/integras are known to break regardless. the only way to do it easiest is a press... Drilling take alot of constant power and hella expensive concrete bits or titanium ones. Normallly it just breaks were it gos into your strut. I have yet to see one break on the subframe or underneath the disk. The bolt is very strong and are all the same and are 12+ dollars at honda! To me the best way of doing it is a press and if your bushings are messed up just get used lca's from the junkyard .. some are prettty good .
