what do I need to swop the front end from a 97 to 98 blazer front end? radiator support and lights grill? wiring maybe? I would love to get this project just wondering how much time is going to be put in it for this swop?

 

There is a sticky posted at the top that says 98+ conversion. Check it out.

Here is some info from that thread.
if you're going to get the stuff @ the wreckers, you need;

-wiring harness for the head lights.
-wiring harness for the signals (not sure if they're different for the 95-97 trucks, but always good to have if you start & find that they are).
-head lights, signals, grill.
-bumper & cover.


*if you do plan doing this, buy a new rad supprt. anything you find @ the wreckers will have some rot, guaranteed.
