I'm not sure of exact years/engines the differences apply to, but certainly later models have LARGER hood pads, covering nearly the whole underside. My '86 2.0E has a very small one covering max 30% of the rear of the hood. Presumably, that is why you see different prices for the '93 2.3 and your car.
Apparently, the difference is quite noticeable, so stick with the full one.. in fact I plan to upgrade myself.
