probably. Its the biggest one around here and has lots of vendors and garage sellers (normally always sells out). Like all meets, its a hit/miss thing for what you're looking for--i suspect the 55 stuff will be available though. Start early when you arrive, its big.
My experiences, for what it's worth. Friday is a good day to be there. There are lots of vendors and the crowd is small. Like lots of swap meets, the vendors crawl the booths early, looking for stuff to resell. Some vendors may not show up until Saturday. Saturday is the big day for the crowds if you are selling, but Sundays are crowded, too. Lots of project cars of every description. The bottom line, it's not as big as Pate or Canton, but I've found lots of stuff at good prices over the years.
