holy crap, i wasnt expecting all these rteplies, thanks EDXR8 for the advice on pulling the bumper off, i will watch for the horn (i dont use it anyhow)
as for where i got it, i went to marlow/repco what not, and bought a daives craig one for $195, looked at it, and there was a ford code on it (i knew ford sold one cheaper, but i wanted it that day, being sunday) but then i thought, $195 is a bit steep, so i took it back monday, got a refund, and went down to my local ford parts, and they sell them, every single bit is made perfectly to put on, unlike the davies craig kit (which is the exact same cooler) and it only cost $140 there, or $135 at coventrys...
so thats how much they cost
as for mounting it, it goes between the radiator, and the bumper, smack bang in the middle, down the bottom, i own an EF fairmont, so the bumper mouht will feed cool air directly onto it
now, all cars have an oil cooler built into the radiator, when one fits the aftermarket cooler, it runs in series with this radiator one, so it feeds into the radiator, then into the little cooler (its very little, about 15cm long, 10cm wide, 2cm thick) and then from there back to the tranny.
reason i bought one, is cause like others i stall it up, and LSD down the road for lots of entertainment, for piece of mind, this little contraption can make a tiny difference to that, also my car gets driven over 500km a week, and im going on a holiday soon, so for that long trip i just wanted to fit one
sorry for long post, hope it all helps.
in short
$140 for it from ford
i own EF Fairmont
goes in middle of bumper out front
is all good
