Hey guys I have a 1990 GMT 400 and I was wondering if anyone could help me find out what size radiator I need. Also I'm missing a part here and I don't know what it is. Can someone help me find out what goes here?

It says 2500 on the side and the VIN came back saying c/k2500. Sorry that I'm not that knowledgeable about these trucks it's my first time working on them.C1500 silverado then?
The VIN should tell you it's either a C (2wd) or K (4wd) but not both. Rock Auto will tell you what radiator you need. The pic looks like an alternator bracket minus the alternator.........
And the truck might be a light duty 2500 (7200GVW)--6 lug or 8 lug?
