R129 brake calipers fir W124??
R129 brake calipers fir W124??
Not all R129s have fixed ball jonts, that's the whole pont Te early ones, even the V8, got pressed ball joints - same as W124
Bigger bearings would also go well with the wider wheels!
As for rear brake - I have no idea yet. 320SL has solid 278x9mm apparently. Same as W124 wagon... Sounds all a bit too good to be true
