Yeah, fair call. I believe (could be wrong) flat tops were 1.5, dished pistons were 2mm ? The set of rings I used on the last lot of these pistons I put in an L18 were a set of 6 for L28 so at least some L28's have them. The first lot of rings I bought at the time were 1.5mm though and didn't fit (ie these ones....) I don't know enough about L28's to know what came in which car. As an aside, L28 flat tops seem to be very desirable and in short supply at the moment. And 86.5mm 2,2,4mm ring sets are also hard to find.
