I recently had the same issue with "Bessie the WonderZ". I bought a very nice used
aluminium rad from a very helpful man in Georgia via fleabay. He included silicon
upper and lower hoses and a Permacool fan. On his car, it was a drop-in install.
Bessie, being spawned from hell itself, had to be difficult.My upper rad hose was right
in the way of the afm housing, even though I am already running a shortened afm bracket. I tried bolting the meter directly to the mount spot-welded to the fender and trimming the upper hose, but to no avail.
Then I hit upon an idea that worked. First, I mounted the coil on a piece of flatstock
that translated it from horizontal to vertical. A bit more room there. Then I blocked the
rad on some wood, *shifting* it over to the pass side about 3cm, and marked the new
mount points with a sharpie. I made sure the top of the rad was level with the upper rad brace, confirmed the positions of the new holes, and drilled.
A note of warning here- the frontside of the rad support is not flat, so have some type of standoff spacers ready. I used cast-offs from equipment installs at work (phone co).
Anything that deals with the bumps will work. My new rad had rubber mounting inserts, but you might use folded up inner tubes or rubber sheet to still vibration.
After getting the rad mounted, I was still very short on space, so much so that the stock boot from the afm to the throttle body wouldn't work. O'rielly's came to the rescue there- aftermarket plastic tubing and silicon coupler kits. A bit ricer, I know, but they work! I actually had to cut the 90deg bends down to shorten them even further.
Now the upper rad hose and the afm hoses are separated by about 1cm on parallel
s- shaped curves. My afm actually is floating between the ricer tubing and the hole in the rad support where the air filter used to go, but it hasn't fallen out yet. Not pretty, but it works. Sorry to be so long winded.
