Actually, I didn't think there was a truck of our vintage that didn't have the bend now-a-days.  Its caused by poor design of the hinges, and not lubricating them enough.  The bend came with the truck, but I have found a place in the same town that quoted me an OEM replacement for around $125! so I will get one of those when I get some extra cash.  
Unfortunatly the bend in my hood has caused a crease in the sheetmetal and I can't really fix it.  A friend gave me a piece of angle iron, and I may just bolt that on to straighten it out till I get the new hood, that way I can at least get under the hood without smacking my head everytime I stand.
You may also try a set of 
THESE.  I think when I get the new hood I'm going to mount up a pair.  My hood is a little beyond the help of these right now.  Try a set and let me know how they work, also... keep those hinges good and lubed.
As for the wheels, they are a set of 
American Racing Steel Rallys that I got at Discount Tire for $75/pc.  I bought the 15X8 size (4" backspacing) and tossed some 275-60R-15s BFGoodrich T/As all the way around.  Makes for a real nice setup.  I was disapointed to find out they didn't come with the trim rings ($35/pc extra) but I can find them for $20/pc new at 
newstalgiawheel.com or I can find a set off eBay for cheaper.  The rims are also a dual bolt pattern, which I didn't care for, but with the trim cap in the center it doesn't show.
As for the air-cleaner.  Its an AdvancedAuto special, 14" Holley Maxflow 360.  I said to heck with it and paid the extra $5 for the Holley name to be stamped on the cleaner :)  Its sitting on top of my Holley 650 spreadbore Carb, which I'm enjoying much more than my Quadrajunk.
