Pretty much the same. I think 93 had a different hold down grommet.
LSC versions have LSC instead of MARKVIII stitched on them (collector editions have Collector Edition stitched on).
I have an org set for my LSC and got a cheapo set from eBay to use day to day (so Icould save the pergect org mats). They were like $35 for fronts and back - perfect fit good color match but no stitching. You can find them all the time on eBay. New , used, aftermarket... Just check the sellers.
All FOMOCO mats have moulded edges - repro and aftermarkets generally have stitched edges.
