Rambler 64 manual transmission.

You won't like the driving with a three speed as much as with the five speed. Five speed conversions are pretty common over here now! Makes the car drive more like a modern car.

You might want to contact the AMC clubs in Finland ( http://www.amccf.com/ - https://www.amccf.com/) and/or the Swedish Rambler club ( http://www.facebook.com/groups/36774550822/ - https://www.facebook.com/groups/36774550822/ ... you can use Google Translate on this page).

They would be cheaper to ship parts from than the US, if they can find them.

Again, you have a Belgian built Rambler-Renault, and from what little info I can find they used a four speed transmission. I'm not sure if that is just a typo or mistake on one site that has been spread over the internet or is a fact. I'm trying to contact someone in the French club to find out, also if the suspension in the rear was changed for the four speed, since Rambler didn't have a four speed until 1966, and that for the V-8s -- the Borg-Warner T-10. Some early Mexican vehicles used the T-10 with a six, mostly Jeeps or HD trucks that used the AMC six produced in Mexico. The bell housings for those (and info on them) are very hard to find!

There should be a data plate on the latch edge of the driver's door. That should verify that it's a Rambler-Renault or imported from the US. Some were imported from the US by small dealerships in other parts of the country -- it's possible one made it's way to Russia.
