heres what I did to make mine fit although the clearance between the left upper a-arm is still tight it does clear ... first I took the upper radiator rubber mounts out of the brackets and turned them around, this moved the top of the radiator closer to the radiator support by about 1 inch also did the same to the bottom ones, then I cut the sides of the shroud down by a 1/4 inch and the inner air passages by 1 1/2 inches, then installed the shroud upside down, now all thats left is to make some mounting brackets and get the thing so it seals good and I should be in business, my car does have a C-4 radiator and the core is thinner than a brass one so this may be why mine clears the a-arm

I made the mounts today for the dual fans heres how I did mine, I took 3/4 inch angle iron that is 1/16th inch thick I then bolted the stuff to the top and the bottom of the shroud, this also sealed up the gap that is found on the top & bottom of these shrouds, I then took rubber sealing stuff (found it at framco hardware store) and applied it directly to the radiator, this sealed any small gaps between the shroud and radiator, now for bolting it up I simply cut sections of the original aux. cooling fans tubular mounts and welded to the angle iron and then bolted them right to the upper original radiator mounts, I havent done the lower mount but that is the least of my worries, clearance wise I have excellent clearance the electric fans clear everything with ease

I'm sure with these mods you can fit this setup to a three row equipped car but I kinda doubt you would have clearance with a four row, or you can just do what I did and put a late C-4 aluminum radiator in mine fit great almost like it was meant to go in there only mods to do this is the trans lines and you have to cut the lower radiator hose just a little, I dont have a digital camera so you'll have to wait till my film is developed and I scan the pics

total cost approx 130.00 and this includes fan relay setup to thermostatically run the fans

will let you all know later how well the setup cools my car but I'm sure if it kept a C-4 cool I should have no problems whatsoever

Very Interesting

I still have 94 fans sitting in a box. I still have stock radiator,clutch fan etc.Making up a strong bracket to hold the fans and shroud both top and bottom is what puzzles me... Can't wait to see your installation pictures and end result of the engine temp.. Also are you running both fans all the time ?Good luck with your installation..

my bracket setup came out extremly strong, I forgot to mention on the factory upper radiator brackets I took and welded the bracket that hods everything to streghen everything since I'm wary of the spot welds they use, I completly finished everything just awhile ago and ran the car up to well over 220 and with both fans running the temperature drop very quikly down to around 190, est about 3-4 minutes, I have a dual fan relay setup to run your fans its all factory GM stuff and has a bracket that mounts to the inner fenders, its setup with two relays and a power feed block, all you need to hook it up, is hook a wire up to the starter, hook a wire to ignition feed, plug the motors in and run a ground wire, and a temp sensor wire, I have this setup on mine and it works extremly well, it will come with almost enough wire to hook it all up depending where you mount it, I put mine on the passenger side inner fender by the A/C compressor and the one I have has plenty of wire to reach everything, I will let it go for 20 bucks

to all interested

my wife brought home her digital camera to and I took quite a few pictures of the upper bracket that I came up with to mount these fans as well as a picture of the clearances that have been a issue with this setup, I also took pics of the fan relays I built to power the fans thermostatically, your probably wondering how long it took to make the shroud fit approx. six hours, I also took a few pictures of the camaro serpentine belt system that I put on the car
