What kind of brakes do we have? Confused...

Wow. Thanks for the overwhelming response. I really appreciate it.

So to summarize, fronts are A-body 1973+, with swapped calipers requiring F-body hoses. Rears are 10" drums. Both front and rear have 4.5" bolt pattern.

I guess that would also explain why the wheels were not stock for the 64 Barracuda. Once I got the covers off I found there were 3 different sizes of lug nuts keeping the wheels on across them all. I think we'll at least try flushing everything like @pishta suggests and go from there.

@abodyjoe I would be happy to look. Sorry for my ignorance, but can you be more specific? Are you meaning the differential? Here's a pic of the diff markings. It's obviously been opened by the amount of RTV on the cover.

I know this is the brakes forum, but I found this stamped on the automatic transmission. Is that a date code of 1979? Could all these come from the same donor car?
