Hey guys i'm trying to find the specific codes for the various PSA's that use the EW10J4S and the BE4. Specifically i'm trying to find the final drive ratios and the part numbers from the 307 Feline, the C4 VTS etc. I have a GTI 180 and i'm wanting to swap out the final drive for a 4.29, which is the supposed FD for both the Feline and the VTS but I can't find their specific codes. I want to go straight to Peugeot and order an OEM FD to chuck in, without any parts numbers/codes Peugeot are no help, they just have absolutely no clue. Also I can't get into servicebox, i'm not a mech so no access.
