ok i searched and have good info on how to install it.
First of all these pics everything was a little dirty anyway what you have to do is there are two mounts that actually hold the radiator in place that have to be removed to get the original out. The top drivers side mount you need to keep. After removing the radiator you slide the new one into place with ease, then that top mount you take the rubber grommet piece and turn it around, basically remove it and stick it back in facing the opposite direction, then you will find a small hole on the bottom drivers side near the radiator tank that you can take a bolt and nut and bolt the old upper bracket to and place the rubber grommet against the radiator to hold it in place, and amazingly the way it fits in there it is snug and does not move at all!! The electric fan is up to you how you want to do that, I used zip ties temporarily but the auto stores sell the special electric fan mounts that go thru the radiator and hold it in place, not sure how to explain but they should know what you mean when you ask for them, comes in a pack of 4. you need a 1/8x3/8 pipe threaded fitting to hook up the overflow line which isn't hooked up in the picture. In order to hook up the overflow bracket you have to cut (to seperate) the upper protruding edges and bend down the small portion that the bracket goes over and you should be good to go, of course you will have to slightly modify everything a little to get it to fit your application how you want it but it does work and great at that!
Yes you need what you pictured, all you gotta do is connect stock line to that connector. I bought mine at an automotive store, was only like 4.99. I connected mine with a tiny hose clamp, although later on down the road I want to do something more eye pleasing.
No, dont bother buying summit universal rad kit. It was a waste, although I did use mine as a template (since it had the proper width of the radiator) for my custom brackets. Although I could have just used a tape measure.
