So far I figure out that
1. All Face lifts are wide body and according to real oem trailing arms are the same as 98 pre facelift widebody
2. 1.9 and 2.0 facelifts has small case and widebody with m8 bolt flanges.
So, if I want to put wide body trailing arms and I've a small case I need to use 1.9 or 2.0 facelift half shaft (33 21 1 229 665). Am I thinking in the right way? In this case I don't need to do anything with output flanges?
