Hello, been on this forum for years lurking but this is my first post.
My question is about the Air Dryer. I was able to get the original part number from Thomas Buses and then cross referenced with my local Thomas dealer for the new part number. It is a Bendix AD-9. But there are tons of versions of the AD-9. The original part number is 108502 that came with the bus. The updated replacement is 065478.
My issue is the deal want $800 for the entire assembly. I found it online from about $700 and up. Then I found the 065225 version online for anywhere from $120-$200. Does anyone know if I need to have a specific version or will the 065225 work? I am unsure of the differences and if they matter.
for reference:
My bus is a 2000 Thomas MVP-ER, been working on it now for a few years
