So here are two links to boosters for the 53. Western Chassis on their power brake booster kit looks like the exact same kit on eBay with a big difference in shipping fees. The problem I have with the eBay booster is that it says it won't work on my 53 Merc in the details, when you enter the info, but it looks just like the one linked here.
I'm waiting to hear back from the eBay seller on why it says it won't work, but honestly I think it would and it would save my some money shipping wise. $12 for eBay and $57 for Western.
Is there some serious differences in these two I'm missing? And if there is, can that be worked out? The car is getting a complete overhaul on the engine so there will be plenty of vacuum to run the booster. The guy doing the engine said it would be easier to install this brake kit when the engine is out.
