Does anyone make a rebuild kit for the 1959 Rambler 3-speed transmission? Are they the same internally as the 1946-1955 Jeep? Those kits are readily available.
I looked for those online when you first posted your troubles, and have only found the same results as you. Hopefully they are the same, because it looks like a lot of parts are available, at least for the Jeeps.
what you have pictured is usually called a "small parts kit", not a rebuild kit. https://hagensautoparts.com/american+motors+-+amc/32-transmission-parts/44110 "Call for availability"
