My 75 Finally Gets The Attention It Deserves(This Could Take a While)

So this past week has been a perfect example of Murphy's Law. I got the pistons installed and then started looking into what would come next, and in the process I discovered that I didn't have either the cam shaft key or the crankshaft key here at my place. It turns out I'd never removed them from the old parts(which were still at the hangar)so a trip to the airport was made to retrieve them. Once they were safely home I went to install the camshaft thrust plate only to discover that it was nowhere to be found. Well holy crap Batman. Now what? I had just seen that part along with all of its hardware, so I knew I hadn't lost it, but where was it? Would you believe it was sitting on top of my toolbox back at the hangar? If you said yes, you are correct. So two days later, meaning this morning, another trip was made to the hangar to retrieve it. Ridiculous I know, but at this point I think I finally have everything I need to resume reassembly. However, based on past performance you may wish to take that with a grain of salt.

Now I have a balancer question for anyone that cares to answer. My balancer seems to be made up of two main parts, a heavy inner disc assembly and a heavy outer ring with a timing mark. Sandwiched in between them is a thick rubber spacer that's a bit deteriorated with cracks and missing chunks. My thought was to bead blast the part clean and refinish it for installation later on. My question is, does anything else need to be done to it to make it usable? Is the rubber spacer OK the way it is, and are there any other issues with these things that I need to be looking out for?
