As the title reads, it took me a while to get this pain of a replacement brake booster completed. I was successful especially using the really long wrench extensions I had to buy to reach the bolts at the firewall from the inside. I test drove my car yesterday up and down a long driveway and discovered the the booster is working fine but the original factory, never rebuilt, 32 plus years calipers are shot. Guess now is a good time to finally install the NOS factory 1LE spindles I bought years ago and all the related hardware that goes with it. Just need to decide on what caliper brand and set up to use. Factory 1LE, BAER, Willwood, or the CTS-V brakes.
