Hey All,

Just got back from the shop. Turns out my brake booster problem was caused by a faulty master cylinder, so I need to get both replaced.

Since funds are tight, I'm not at the moment able to spend the $600+ for new parts. So I'm looking on car-parts.com (Online Junkyard database) for my replacements.

I've hit a problem though. They've got two master cylinders listed:

"123 Type, thru ch #054824
123 Type, from ch #054825"

How do I know which one I've got?
