I looked at the R/A listings
My big concern with auto parts stores, both brick & mortar as well as online, is so many parts are shown to be for the ZR-1 & LT5 that are not. hence the reason to find one here.

PN history;
1228331
16163860, superceded by 16163993,
16163993, superceded by #88999186 (GM rebuilt exchange)
16196394, superceded by #88961142

Parts manual;
1228331 not listed, but ZR-1 net Registry shows to be for 90-91
16163993 shows to be for 92-93
16196394 shows to be for 94-95

Compatibility;
16196394/88961142 works for all model years, 90-95, with correct prom for vehicle model year.

Other Rock Auto PN's;
Cardone #777727 (OE #1227727, 16197128, 16198260) appears to be for 1990 VIN Y (L98), not VIN J.

ACDelco was deleted from the system when I tried to order from R/A. ACDelco actually has quite a bit in their catalog for the ZR-1, but is NLA when an order is placed.

Summary:
I have ordered the only one of the 5 remaining listings that was not Return & Rebuild. We shall see what arrives!
UPDATE: NOT AVAILABLE, ORDER CANCELLED BY ROCK AUTO.
