I contacted polarbear. Waiting on response.
So it had a fan shroud? I know I can't use the brakes since the swap won't work on 2wd and I'm considering going 2wd with my diesel to see what kind of MPG it can get and since I'm not keeping my 2nd gen too much longer so I need an economical truck not a off road beater truck. It's driving me crazy. I put a new exhaust manifold on today and the O2 sensor seized so I need a new $95 o2 sensor. Also the back head stud broke trying to tighten it. I barely got it snug and it snapped. Luckily there was a few threads to tighten 2 nuts on it (since I didn't have my stud extractor set) so I had to pull it out and luckily I had a bolt with the same threads but I had to put a nut behind it cuz it was too long. Looks tacky but it works.
