I have a 1975 FJ40, made in February of '75, and two of the posts that hold my master cylinder to the brake booster have broken off. I want to know either a: Is there a way to take out the broken posts and replace them with new ones (which may be difficult), or b: What replacement brake booster can I buy, hopefully a used one, and from where to replace it at a fairly inexpensive cost. If anybody has a brake booster or a suggestion I would greatly appreciate it.
