I came across this information in a previous thread. But here is my situation. I have a 1992 Pontiac Bonneville SSEi. I am the original owner. I had a LIM leak (between the LIM & Heads). When working on it today, I discovered a previous repair (likely by a dealer) when they put in a replacement thermostat a long time ago - had lots of sealant around everything. When taking it apart, there was a lot of corrosion in that thermostat seat, and pitting all over. I can see why someone tried to make it work now. There was also a problem many years ago getting that heater pipe that goes into the front of the LIM (pipe has an o-ring and is held in by a bracket), and that also had a lot of sealant from a previous repair.

Anyway, there is enough corrosion there that I don't want to put this LIM back in. Of course, there is no dealer option to put a new one in. I went out to the salvage yard and found 2 possible LIM's, but both were from 1995 vehicles (one an SSEi, the other a Buick Riviara) The one in the 1995 Riviara has a black coating on it, while the one on the 1995 SSEi is silver, just like my 1992 is. I know the 1995 SC'd vehicles had a somewhat different Eaton blower on them, but the LIM looked a lot alike. I don't want to go to the trouble to remove one of them to find out it won't work. Any inputs if a 1995 LIM will work in a 1992 application?

My LIM GM part no. is 24501562. I don't know what the 1995 LIM's GM part no's are, but I think they are 24502302, from what I could barely make out with them installed. I don't want or need the 1995 SC's, as I know they won't work properly in my 1992. Just want to know if the LIM from a 1995 is identical to my 1992 LIM.

There are two versions of the 92-95 L67 LIM. In 94 they added some interior baffle walls that seem to smooth out intake noise. I've had both on my car and that's the only difference I noticed. They are swappable.
