Good luck with it. I started on mine wanting to fix a rusty floor and it turned into a major reconstruction deal.?

Today is the day to replace the check valve for the master cylinder power booster.? The new part appears to be a perfect fit but is not 100% identical to the?old one overall,?however close.?
Removal of the old check valve did not go as planned.? When I glued the check valve back together so I could drive the car home safely, it bonded to the rubber grommet also.? I could not separate them so I had to remove the check valve and grommet together.??This broke the part of the check valve that goes inside the grommet.? I pretty much expected that.? Unfortunately, as I pulled them out some of the broken check valve fell into the booster.? That meant I had to remove the booster to get the pieces of plastic out.?
To get the booster out, I had to remove the master cylinder.? Once I did that, I discovered it had a small leak into the booster.? I have not taken the master cylinder apart yet to see if I can rebuild it or buy a new one.
I was able to get the plastic pieces out of the booster but realized I needed to open the booster to clean out the brake fluid that had built up in it.? I cleaned it up and it doesn't look like the brake fluid damaged anything.? It appears to have been rebuilt at some time because there was some pitting where brake fluid?had been sitting before?and caused some corrosion when it absorbed moisture from the air.? The was no rust and it appears to have some kind of corrosion resistant finish on it.? So, I know the pitting is not from the brake fluid leak this time.?
Once the booster was out I had good access to the shifter linkage.??The linkage?has always had a little play?in it but was not bad and I just lived with it.? Of course, could not help myself and had to take a closer look at the linkage.? I found one of the connections is worn and I will probably take that apart to see what I can do to repair that.?
I need to stop looking elsewhere or I might have the whole car apart.
