That is a factory 93 mount. If you read closer on RR's site you select 93 if you have an Autozone mount not a factory 93. There is not an insert for that style. You should be a able to get an aftermarket rear mount that works for the 93 style inserts for about 40 bucks. I did the same thing, if you need the anchor part number I can dig it up for ya.
What year was your car actually built? Mine was built in late 1994 but it was sold as a 1995. Some of the wiring is different than the 1995 wiring. I think Mazda tried to use up some of their leftover parts on late year production vehicles.
