Awesome, thanks, Mik! I will print those out and bring them to the shop. It does look like one inch, maybe 1 1/4. You know though, for just that little, I wonder If I could get me a come-a-long and pull it myself.
The Blazer is in the driveway facing a 1965 Ford Galaxie. Seems like that would work if the cars wouldn't slide and the core would bend back in the same place it was bent back, if you know what I mean. Maybe too many "ifs."

Ive bent them back before after hitting deer or trees offroading, guarantee you could do it with a come a long, ratchet strap or just throw some gloves on and yank on it, they aren't that solid at the top. and the position is more dependent on the top mounting bolts that connect to the quarter panels so its not so much the support than it is bending the mounts back on the quarter panels where they used to be to the support near the headlights and maybe pulling on the radiator support, also the hood latch bracket I found you can just bend with your hands too if it doesn't line up right with the grille mounts/hood.

if you remove the bolt and there are 2 others holding the support to the fender if i remember correctly near the one circled in this picture and pull on the support it will come forward and you'll see what I mean.

 

Mik you have inspired me. I'll give it a go myself. Ill hit autozone after christmas and pick up a dent puller and HF for a comalong, maybe between the two I can get this baby straight.
I think you are right that the bottom of the core is still fixed to the frame and is ok. As far as I can see, the core is held up mostly the fender, like you say, so I suppose that means the fender needs straightening also. I see 4 bolts on the pass side, I've pulled the top two (maybe I should leave them?) and will loosen the bottom two. Then do some hammering and bending on the latch support. Weather permitting I'll give it a try Sunday.

If anyone has advice between now and then, post it here!

 

Hook it up to a thick tree.

After looking at my wife's blazer it looks like it's been pushed back also. Lol

 

Pictures and measurements from my Blazer:

 

Thanks Lanny. It does seem to be that I am on average 1" back. A little less on the driver, little more on the pass.

Regarding the bolts holding the core to the fender, I put them back in. Maybe if I can get up enough pull, the fender will straighten up along with the core.

Weather coming in, might be a few days yet to try.

 

Okay, I got the comealong and pulled the core back! I think its going to work out. Pulling straightened out some of the crimping in the fender but in the end I unbolted and straightened out the kink that you can see in a previous pic was about one inch behind the bolt. Separated from the fender you don't even need a comealong to pull the core, just like mikmac said. Measurements all look good.


I bolted in the top of the hood latch support but it was bent in so bad the bottom hit the bumper. I'll see if I can bend it back myself, like Micmac says.


Now the old air baffle, the big rubber thing, was ripped so I bought a new one. I'll try to squeeze it in there but may have to take off the bumper. Is that a challenging job?


It's not going to look new like it did before but it's only cost me $200 so far, for grill, lights and baffle. Thanks all, for your support.

 

The front end replacement job is done, done enough to get the car on the road. First I pulled the bumper off enough to get the baffle in. I ended up getting a new latch support($40), just couldn't figure out how to re-bend the old one back the right way. Got an all chrome grill from Amazon (avoids painting) and a set of parking/headlights from ebay.
Try as I might I could not get it all to line up, I think the core support was bent in where the headlights attach, anyway I took the pieces in to a local guy and he set them in properly for $200. He offered to paint the hood and fenders but I think I will do something there myself
The Blazer is not new-looking now, but is good value, for me.
