Hi for All members 🙂

I need some help becouse i dont find the correct infos in the Peugeot/Citroen service program 😞
I have a 306 Rallye car with XU10J4RS and 20TE47 gearbox from a Xsara VTS.
Can somebody give me informations about a shorter final drive?
I know its a BE3-BE4 box what is called BE3R IIRC…
I can source the following gearboxes but i dont know its fitted with a shorter drive and can fit into this box 🙂
-20TA74 -its looks like a BE4
-20CH46- looks like BE4 also
-20CH44 -BE3 i think
-20CH47 -BE3
-20TE20
-20TA75
-20TB12

Somebody know the correct gearbox code for this swap pls let me know

Thanks )
