How I fixed my Hood from raising up in the rear even though new hinges were installed

[520CheyenneK10]

OK race fans heres what I had going on with my 73' Cheyenne Super K10. Bought the rig and the hood hinges were worn to hell and the springs were shot like usual for a 40 yr. old truck. I bought new sets for both side from LMC and marked the old ones on the inner fenders and the hood on each side and installed. Well the damn rears was still stickin' up so I scratched my head and tried all I knew. I am not a big fan of altering holes and such but I did oval out the two forward fixed holes a bit since when I removed those two slotted ones and pushed the hood up so as to set the two slotted ones I could then reinstall the fixed ones. I did all that and lubed the hell outta the springs and all the pivot points on the hinges and still was up in the rear next to the windshield. I then got on line and looked here and even posted but got nothin new. I did a search and seen in another Chevy forum where a guy mentions his buddys hood flew open going down the highway and it pushed it up so hard that when he closed it the raising in the rear problem was no more and the hinges were fine. So I decided to give it a try and since I'm a 165 lbs. of raw hide and spring steel I knew I didn't need to take to the road so I stood on a 2 step stand and pushed like hell right in the center of the hood and i'll be damned if it didn't work. Hell I opened and closed it a dozen times since to make sure and it's still down in the rear. I don't know but I figured I'd let all you all know what I did since all the other threads and post on this subject seem to really not have a solution.
