80-73 Front end swap

[HumbleChevyBuddy]

Ok, so I've been making good progress on my 80-73 front end swap, however I seem to have run into a bit of an issue and I'm hoping ya'll can help me out. Because my 80 had the rectangular set of headlights, there was a headlight mounting bracket that the headlight buckets bolt on to. On to some pics and you can read what I'm having issues with.

Here is what it looked like before making any changes:


Here is what it looked like after I removed the old front end parts:


Here is how it's coming along:


Now, here is what the 80 headlight mounting bracket looks like:


What I'm wondering is, do the 73-79's also use headlight mounting brackets? Or do the headlight buckets mount directly to the core support? If someone could post some close-up pics of how they mount, I would greatly, greatly appreciate it.

I'll take better pics after I'm all done and post up how I did it all and what parts I purchased to complete the swap in my build post. Thanks guys!
