The shells fit so that the anti-rotation tabs fits into the cut outs on con-rod and end cap respectively. Not known for there to be a top and bottom but that's a good question that needs further research. When I rebuilt my 33 engine there were two grades of shells available for the same size e.g. standard, but one number was for a regular tolerance and the other was for a tighter tolerance, I went for the closer and that engine was still running 140 000 miles later.
Looked it up for the TS in GTVs, the 1.8 engine details are as follows:-
Class A (red) i.d. of con rod half bearings/mm = 50.835 to 50.855
Class A (red) diameter of con rod journals/mm = 50.799 to 50.805.
Same as for 2.0 TS.
Clearance for 1.8 is, in mm, 0.026 to 0.056.
For 2.0, 0.03 to 0.056 mm.
Assembly states "House the half bearings on the con rod caps.......the safety notch towards the same side as the corresponding notch on the connecting rod big end". No mention of a difference between the shells/half bearings.
