1960s 1950s GM Chevrolet Chevy transmission manual standard 3 speed 1957 car?

Description

I have several more pictures of the inside gears and transmission itself as well if you want to see them send me a message.
Here is a transmission.  I don't know what it is out of, so use the part numbers to determine fitment for yourself.  This is sold as a core for rebuild only.  As you can see, the gears do have some wear/chipping on them from grinding the clutch.  The gears are also dirty.  It spins, but doesn't spin fully or shift correctly probably because the dirty gears as shown.  Use the part numbers and pictures to determine what it will fit because I'm not sure, this one is earlier than I'm used to messing with.  I will answer any questions that you have about it.  Local pickup would be a lot cheaper if you are interested in that message me.  U
se the pictures and ask any questions that you may have.  Again, it may need rebuilt completely, so buy it as a core or for parts.  Yes I will ship this, and shipping cost is free at this price.  If you live relatively close, send me an offer, shipping varies quite a bit on these depending on distance from me, so I can take less if you live closer of course since I'm paying shipping.  Let me know any questions you have.  If you are a transmission core buyer and are looking for several transmissions from the 1950s-1980s, let me know.  NO RETURNS.  Sold as is, as shown.
All of these items may have
scratches, nicks, could be dirty, etc.  Use the pictures to judge condition farther.  Sold as is.  Shipping is to the lower 48 states only.  I will answer all questions.  I take feedback seriously.  Please leave me good positive feedback and I will do the same for you.  Check out my other listings!
