I changed my '89 to a '95 FACTORY front bumper. It fit fine. The bodies of the two styles are the same. You do not need to measure! Your shop needs to know what they're doing to get it right. See my customizing my '89 thread for a pic of my front bumper.
Where the inner structure bolts to the frame, there are up/down and side-to-side adjustments. Where the facsia attaches to the inner structure, you can also alter the gap line (up/down & in/out). I believe this can be accessed with the hood open -- along the top edge of the bumper. This adjustment can get your gap parallel and/or level with the hood.
I assume you went to the correct inner structure and aren't trying to fit a late facia over an early inner structure. You should not have to order an aftermarket bumper. You should have to get an experienced shop mechanic who's familiar with these older cars to get the alignment right. Younger guys may not figure it out. And, they are a pretty big pain.
They probably did not fit the bumper to the car before paint. Ideally, this is what should be done. IF the bumper cannot be adjusted to fit -- with a good gap -- the bumper can be shaved to get one.
In my opinion, you have an issue with the shop, not the part. But, then again, I can not SEE what the issue is. NO PICS!

Gregg, Sorry about not having taking pics yet. I work Thurs and Fri and they are closed long before I get there. Sat I'm heading down there and raising hell. I have $2000 in the bank from the initial appraisal, so he can fix it or lose more than half of the cost of the job.
If you mean a 91 to 96 inner structure, the shop ordered everything for the the late model fascia, or so I was told. As far as fitting it before painting, I assume they didn't or they would have contacted me about it, then the adjuster to see what he would do about it. As of now, they are trying to make me settle for what is the worst looking Corvette front end I have ever seen. I am not going to settle for such a horrible job, and told the adjuster that. But, it looks like it is the shop who is at fault here because they simply can't figure it out.
I called Varacor who handles aftermarket everything, and talked to Diane (co-owner with her better half for over 20 yrs), who is one heckuva great lady. She measured the fascia in the front corners, also how high it was from the floor, then measured a hood which was there because it hadden't been picked up yet. The fascia and hood measurements were the same. It is hard to measure my hood on the car, but I am going to try. It should be the stock hood, but as luck would have it, I called the guyt I bought the car from, and his # is disconnected!! Oh yeah, Diane also agreed that the ploy fascia should be workable, by someone tugging and someone ratcheting. That will be told to the baod man Sat also. Can you think of another or better approach? Thanks for replying, and genuine concern.
