jes - they come with nails, rubber seals and metal clips that slide through your radiator and fasten to hold it in. nothing special, just the industry standard for mounting aftermarket fans. have 2x14" fans on my supra held on this way. the fan fits behind the left radiator with plenty of room to spare. it's a tight squeeze on the right side but will fit.
i got it from proairllc, $42 fan +$7 shipping. **make sure you buy a pusher, you cannot reverse the blade on the spal**he does not have any for sale right now on ebay ( i bought both of them) but i shot him an email and asked him for a contact to try and skip over ebay so he may drop a buck or 2 on the price. once he sends me that i'll post it for everyone.
you may be able to find a cheap fan mounting kit on ebay for a few bucks, i ordered directly from spal and you need 3 per fan, but shipping is rediculous at like $10 or $14 something like that for 6 little pieces.

digby - Thermal Dispersant Coatings!
that's just a website i pulled up, procryo.com/ evan's performance out of atlanta does all of my engine work and i would recommend them, but they don't list tltd on their website.
basically it's a coating that improves the effeciency of any air cooled device, on the supra it cost $140 to get the fmic done, but i seen almost a 20 degree charge temp difference at 18 psi. worth every penny. i thought since it works so good on the intercooler, i'd give it a shot on the rc rads and oil cooler this winter
