He is working on an IDI. I believe his truck is a Bricknose, that he did a "nose job" on and transplanted an OBS clip onto. So the install would be "like" a 92+ install since that is the core support and grill he is working with. On these trucks, the OBS (92-97) clip is the "easiest" room wise to install an intercooler. Then the bricknose (87-91) and lastly the Slantnose (80-86). The back of the grill is deep and goes back closer to the radiator than the OBS grill does. On the 94.5+ PSD OBS's Ford did stuff and intercooler in there....... but the core support is different to accommodate the piping and I have read the radiator is not as thick as the IDI radiator......
I'm not a fan of using steel pipe for intercooler setups. The insides can rust, and then you've got rust particles going into your engine. Alluminum is a must in my mind. Ebay is where I got mine.
i would not mind aluminum but i can't TIG it, and i don't want to have a bunch of silicone couplers on it, mainly b/c the silicone is expensive.
If you have a TIG just practice practice practice and you should have no problem welding aluminum. You can also use stainless steel it is easier to weld than aluminum and resists rusting.

he's got the right idea of mounting the IC exclusively on the radiator support. problems arise when you mount the lower IC on the frame and the upper IC on the radiator support. There's a reason why there is a thick rubber mounting system between the frame and radiator support, ford accounts for an extreme amount of flexing between the frame and body. The radiator support is part of the body. need physical proof? go find a curb and drive one of the front wheels on top of the curb and the other on the pavement. get out and take a look at the relation between the bumper and the valance panel above the bumper.I dropped in a 6.0 intercooler in my 92. 1" square stock welded to the frame and 2 bolts welded to the core support. Never had to trim the intercooler or anything. Trim the core support a little, and the rad side tabs. That was it.
