Just measure the seal housing diameter on the gearbox (outer diameter), shaft diameter (inner diameter), and thickness of the old seal. These are the dimensions you need.
The driveshaft seals are easy to find, try to get double lipped ones.
The primary shaft seal is directional (clockwise rotation), you will notice that it has small ridges around the sealing lip. This must be taken into account, and if you can't find a standard seal like this, you will have to buy it as a Renault part. These seals are "offset" on some gearboxes, that means the sealing lip is not located on the seal centerline. It is better to use that offset seal, but you can also calculate where the sealing lip will be located and determine whether you will be able to use a normal seal, or an offset one. On the R4 gearboxes it is possible, I am not sure if the 5 speed gearbox has any difference on this.

This is getting better and better 
Here they are, the little one is primary shaft seal and the big one os drive shaft seal.
The dimensions for the big one are 36x54x7.5mm and it can be found on franzose.de. The little one is 17x28x7mm and it has small ridges as you said...
The thing is that franzose.de lists only 17x28x7.3mm (ok, 0.3mm will not be the problem because there is enough space to fit it) but it doesn't look the same, it does have ridges. angel would you be so kind and take a look at this http://www.franzose.de/en/Renault/R4/Radlager/ANR83013/ Is that what I need? Thank you.

If these are the seal dimensions, this is the seal that fits. There is a 1mm difference on the seal outside diameter on the left-hand turning 354 gearbox compared to the right-hand turning one, exactly for that reason, not to fit the wrong direction seal by mistake.
The franzose.de seal is the "offset" type (look where the seal lip is, compared to yours). It is OK to fit either seal type, provided that the seal lip contacts the machined section on the input shaft (this can be determined with careful measurements).
Seems also that they made a mistake by specifying two seals necessary for each car, it is definitely one there, and this dimension is not used anywhere else on the car.

It has to do with the orientation of these tiny ridges on the sealing lip. They act like small channels, to direct oil away from the sealing lip when the shaft rotates. If you fitted the wrong direction seal, they would encourage oil to flow towards sealing lip.
Directional seals are marked with an arrow on their outer side.

are these direct fit or do you need to apply a silicone sealant or something to fill gaps?
