This clearly has the unique Chrysler inlet flange pattern. The TIII used the universal TO3 or what some people refer to as the Ford housing. Attachments below shows the rectangular TIII Ford style housings. Last picture shows the two inlet flanges (Chrysler and Ford) side by side.
You would also need the appropriate coolant feed and return fittings & lines as well as the turbo oil outlet drain tube, as these are different than the Mitsubishi turbo.
BTW - The turbo you pictured appears to be an 88 TII model which has the small 2-1/4" swing valve but with the larger downpipe flange on it. The 89 TII model (third picture) would have a true 2.5" swingvalve with a large wastegate can actuator. This would be considered a small upgrade over the 88 model year.
Hope this info helps,
