I've had a bunch of mk3s, some pre 89 and some after and I don't recall seeing that shape on the left.those floor mats are awesome!
Does anybody know why there are 2 different floor mat shapes between years? I think the cut off year is 89.
Here's a side by side comparison of the 2 different styles on the driver's side available from AC custom carpets I believe. These shapes are different than the Japan one in the OP.
