93 uses a tpi screw in iac.
94-97 has the iac housing as you have shown. Here is one for cheap.

There is little clearance on the left side water outlet and the t stat housing. The last one I used was on a stock tpi. I’m not sure but there maybe clearance issues with the manifold on aftermarket bases and runners.
here is the wiring. The square 4 connector is female unlike the picture.

You can always cut the iac housing down too.
if you need a gasket kit autozone has gp sorensen
96-3008
If you have a serpentine belt setup Dayco 87662
works well to bypass the throttle hoses. It runs from the front intake coolant port to the heater control valve.

Although I have a 91 I’m running belt because I’m running alternator and power steering. I’m running the stock but ported tpi base and plenum
i got the housing today I dug our a couple of iac actuators I collected over the years from body part outs. I’m not sure if they will work. They both have to be mounted with screws and harness adapter. Is there a specific part number on the iac ?
