alright, fair enough, you got me there...but read over this (you obviously didn't read as thoroughly as i asked you too...and i was so nice about it...) and GM will tell you the reason the K-series are different...

"In August 1983, the GM engineer in charge of the tests posed the question, "Why is the C and not the K passing the test?" and "Why does the tank crush differently front to rear on the K-truck?" To answer these questions GM conducted additional testing that established that both the increased truck ride height and frame stiffness were subjecting the fuel tank in the K-series truck to different forces than those experienced in the C-series truck."

i didn't make this $h!t up...if you look on this attachment http://autosafety.org/GMAttL.pdf on page 5 and read, you will see EXACTLY what i typed. still wanna tell me its the same frame? the basic frame MIGHT be the same (it is about the same thickness c-channel, i'll give you that) but the crossmember position and other subtle things ARE different.

if you don't believe that, don't even bother posting in here, write yourself a letter to GM and you argue with THEM that the frames are the same. you convince THEM and $h!t, i'll believe ya too and even buy you a beer.
