How To Get This Front?

[modmach1]

Hi There !
Im new to the forum here and just surfed the web for 73-87 Stuff. Im going to buy a 80 Chevrolet C-10 Custom Deluxe pickup Fleetside Long Bed. The owner is fixing up the bed in these days and i can pick the baby up i about two weeks.
Heres a picture:


And here is the deal..im gonna change the front either to 89-91 Suburbans or to the front in the picture below...i know that i must change the fenders, inner fenders, hood etc..to the 89-91 Sub front.. But what must i change to get this front? and when came this front? and how long did it go up on the 70s?
