1946-49 Plymouth Transmission rebuild. Where to get parts

[49-P15]

I an rebuilding a 1949 Plymouth 3-speed manual transmission.  I would like to scare up a reverse idler gear and the mating low/reverse sliding gear and thrust washers for this transmission.  This transmission was used in most Mopars of the era.  There must be a ton of gears out there but I don't know how to locate them.  any ideas or sources?

Ebay. Buy NOS. Helps a ton if you know the actual part number. 
 

If you need it let me know. Can provide. 
 

I can also suggest a seller to avoid. PM me as I won’t post seller’s name here.  Thanks.

Thanks Kieth,  I can scare up the Mopar numbers but I'm not sure how to convert them into supplier numbers.

You search a Mopar part number on eBay. Options will appear.

I found some thrust washers yesterday.  But locating the gears is more difficult. 

 

I'm thinking that the gears that I have are in decent shape except for the beveled ramps which have been banged about somewhat.  Why couldn't I just kiss them with my dremel and clean them up a bit?  How critical are  those bevels since this is Reverse gear?

 

Is this harebrained?

Northwest Transmission will have a great rebuild kits but not hard items like gears.  I've had great luck with their rebuild kits on several orders.

Are you interested in a complete transmission from a 49. Looks and the true inside can be deceiving (First wife comes to mind).

I've been told not to mess with the gear-teeth bevels since they are surface hardened and that surface should not be breached.  So, I'll use the best of the gears that I have.  They are not too bad but the purist in me would prefer new ones.

Vintage Power wagons has gears and other items for transmission rebuilds. Maybe they have access to automotive parts or know where they can be found.  Might ask them to see if they do. They are very good  to deal with even if you aren't buying something.

They are hardened and also need to mesh flat with the other gear or it will make a lot of noise.  I will do my best to remember to check on a business card I have for a fella that sold me a new cluster gear for my 54 Special 3 speed.

  Try Dennis Marordas     606 237 6648.   He had parts for my Buick.
