Re: think these are the same parts?
Thats the correct part. Listing it as an IAC rather than ISC is probably a catalog error. I've owned many Cadillacs that use this part and have yet to replace one. Almost every car I get, someone has monkeyed around with the adjustment. Just got a 91 Allante and it uses the same ISC as your 85. Someone had shimmed the ISC away from its bracket to lower the idle. I retracted it by the book, then adjusted the minimum idle to spec then found it necc to screw in the pintle two full turns to get the proper gap. I've even taken one apart and cleaned it. Rather a simple switch when apart.
