I am in the process of installing the front bar into a non bar cavalier. Does the drivers side hole in the sub frame need to be tapped for the bolt or is it already threaded? A real pain in the posterior getting the bar in place but I am sure it will be worth it. Can anyone also recommend a good rear strut bar? I have the GM one out of a Sunfire convertible. Just need a good one for the rear. Thanks in advance for the help.

Holes are tapped. Only a pain the first time, once you know how it's easy. Rear strut bar, find ebay's cheapest....
