if you have a 67 core support to match up, the major differences are where the front pan bolts to the 67-68 core support. Drill holes, use rivnuts and that part is done. The head light buckets are different, the core support mounts are different, the 67-68 turn signal lights use holes in the core support.
I looked for almost 2 years to find a perfect 67-68 core support. I listen to people saying there were no alternatives. I was putting together a 71 front end and looked at the 71 core support. I put my rusted 67 next to the 71, all the important stuff is the same, the minor differences aren't hard to fix.
69-72 supports are a whole lot easier to find.
