Yep 2732A. You really should buy 7747 though as the bin files, ecu files, and patcches are more readily available. More people use the 7747 becuas it is not the 1 year only ECM that the 299 is. The 7747 is a direct swap for the 299. My 1992 van TBI setup had the 299 and I went to a 7747 out of a Astro.

7747 refers to ECM type. The full part number is 1227747. Chances are you don't need to swap anything to switch ECM's, but to be 100% you should compare the wiring diagram for your model to one with a 1227747 ECM.
