Tranny Cooler

I've installed a couple and the FRPP is a nice piece. However, I'd get one with screw in barbed fittings (like the big B&M).

I would not sweat the install kit stuff much if yours does not come with it. You can get hydraulic line at the parts store (and very well might need to anyhow if you have to run the lines very far. Or make your own hardlines. It doesn't take too long).
And you can get some bracket stock at the home store. I would not use any pull-rough ties.

Just MHO.
Good luck.
