Despite being listed in some catalogs as a \"Switch Kit,\" this is specifically the breaker-point\/contact set that sits inside the distributor — not a dashboard switch or battery isolator.

This is a distributor breaker-point set, and it only fits engines with a conventional points-style ignition system. The critical fitment check is the Bosch distributor number on your engine: if your AQ130 shows distributor 0231178011, this is your contact set. If it shows a different distributor, verify before ordering.
