In answer to your question on interchanging hoods between 359 and 379 model Peterbilts, I would have to believe you can. Of course, that is providing the two trucks are either both standard or both extended hood variants and are of close to the same year (older Pete's had intake ducts coming from under the hood ahead of the air cleaner canisters, causing a notched hood like on a Kenworth W-900 to clear the ducting). The 379's and 359's were built using the same platform, with only a few specific differances. For example, the 359 had an embroidered quilted pattern on the interior door panels with a few western-like designs around it, where as the 379 had pretty much the same door panels that it did until the end of it's production. There were other slight differances to the exterior, such as primary reserve air tank location ( 379- under cab above battery box/ steps, 359- normally ahead of battery box or fuel tank, where the air dryer is located on the later model 379's). None of these differances however effect the hood itself. The dimentions and the mounting are the same. I have owned two 379's in the past and I now own a 1984 359 ext. hood which I restored to original factory specs using many 379 parts in fact, though the hood, as it were, was in good shape. My current project is a 1984 362 Pete cabover, and believe it or not, the doors and many other parts are the same as a 379 as well. It only made good business sense to make so many parts interchangable between models. It was not intended to be conveniant for us, but to lower production cost, rather than having to build everything separate per model. Good luck with your project and I hope I was of some help. -Brandon

the answer is NO. you may have no problem setting the front pins in the hindge, but the rear of these hoods vary. first, the 359 has cut outs where the air breather tubes lead into the engine compartment, the 379 does not have these. second, the lower part of the hood, near the back of the fender, though they look similar, each has a different configuration of supports to hold the back of the hood. if you love your peterbilt as i do mine, you will put the appropriate hood on it. after all, it is a peterbilt. my info comes from owning a 1987 359 ( #9 of the 359 made that last year) and a 1988 379exhd. hope this helps. outlaw379

(the answer is no) correct outlaw but it's not intake hoses or like branded talked about battery boxes,interior desine. the 379 cab was a new desine the cab is about 8" wider the ultra cab was wider and taller yet. it's nice you guy's can point the stuff that's out in the open, and knowledge on where air tanks and fuel tanks are and the battery box's are but simple answer to a simply question is no 379 hood is to WIDE. if you own a 359 then you know the joke about why there is no u in peterbilt..........there is no room for u and i. skbtrans

no no no you might as well try to hammer a mack hood on your pete! as for as the size of the cab on a 359...if she won't fit between the seats you don't want her under your sheets!!!!!
