The idea you have here is awesome, good find and a nice job done by the them.
BUT.....not to be a downer, but this is about as bad as a Ford guy with his 4" lift/33's on his F150, that replaced the badges with F550 emblems and think his truck is badass.
A Dana 60 and 14B does not make something a 1 ton.
Unless..... you shortened a K30 frame that you put in your blazer, used both front and rear springs from that K30, and.... dead last and the least important, installed the components that allow the weight handling of a 1 ton, like the
axles.
If you have ALL of these things, then I'll insert foot in mouth, you would indeed have a K30 Blazer. Otherwise..... it's a 1/2ton K5 with some big axles.
Sorry, but this is just something that erks me sometimes.
