Tell me about it- lack of upto date/ item specifc images has always been a pain in the r/c world, makes me have to 2nd guess everything I look at sometimes.
The last 2 pictures you posted especially make me think those are combos and not hybrids- the hole/ recess for the bearing to sit in should be exactly the same on each half - Im gonna assume when you tried fitting the bearings that came with your 1/8 diffs, one side was fine, the other isnt even close (not just a tight fit which is normal, but a good 1mm or more too big to fit)?
If thats the case, FLM should sort you out, but getting hold of them is a pain quite often. Just keep the emails civil to avoid them blanking you..
