I think at this point, I'm not really looking for what 'should' be there as much as will the 67-68 mounts work without other issues such as the bumper. Will the 67-68 core support mounts actually lower the core support closer to the frame, and will this be an issue.
I see you ended up using 67-68 core support mounts. How did this end up working for you? Any issue that you can share with the installation, or have you had any issues since? Did it help correct the alignment between the fenders and the cab? Thanks!

For the record, my truck is a 69 3/4 ton 2WD produced the second or third week of December, 1968. I'm 95% positive that the truck came from the factory with the 67/68 style core support mounts. The only reason I'm not 100% sure is that I was hit in the left front in 1972, and minor damage was done to the left front of the core support. The frame was not damaged. I don't believe the core support was removed from the truck when repaired, but when I did the restoration the left mount was assembled differently from the right mount. The core support brackets on the frame appear to have the larger hole and are basically flush with the top of the frame (see 1st pic below). When I did the resto, I replaced the core support with one from a 70, 71 or 72 and used new rubber cab and core support mounts that were the original style. The cab mounts were those specified for 3/4 ton and 4X4 trucks only. I ordered core support mounts for 69-72 trucks as well as those for the 67/68s.
I first used the 69-72 mounts and had a gap problem similar to yours. When I examined the repro 67/68 mount kit, I noticed that the washers supplied were a smaller diameter (too small for the frame bracket holes) than those original to my truck. This would be consistent with the belief that 67/68s had smaller bracket holes. So, I installed the 67/68 kit with my larger washers. The gap was corrected after applying more torque than specified (see 2nd pic). The bumper alignment is great (see pic 3).
