Do you have the old
suspension taken apart already? You should be able to just put the two bolts through the inner fender, and then reassemble.
But from your question, it's hard to know for sure where you are in the process. Are you rebuilding the stock front end, and on what year of car? Did you buy new
control arms, or just new bushings? Do you have a vice to work with?
Got any pictures of what you are trying to get done?
