seen friends do the same thing.Ok I didnt read al because there was some drama I started reading...
Anyway.
To just swap the bumpers, short answer no. Long answer, you have to adjust the mounts on the GMC bumper to get it to even bolt up.
now, once you do that it will look like ass. (trust me Jordan, you will want to fully convert it after you get the bumper to fit, lol) there will be a huge gap at the top of bumper. to do this right you need:
bumper
fenders
hood
grill
headlights
(yes the whole clip)
Also I want to say we used the radiator support from the GMC too.
Reno, my buddy started this project with the same intent, just the bumper, a few hours later we were back at the junk yard picking up the rest of the front end.
I have a few pics but there not digital....
if it is possible to some how make it work without doing it all, id love to see it
