Got the PM. I'll put them in the mail Monday.
I attached the tops before I attached the bumpers. I used M6 self-locking stainless nuts with stainless flat washers.
Fog lights are currently attached with body bolts- like a big sheet metal screw. I'm going to pull the front bumber off and reattach using a captive nut of some sort this spring. Horns attach inboard of the two lights the same way I think.
Tricky parts of the changeover? Well, I guess aligning everything, and especially centering the bumpers so the overhang on each side is identical. The holes are a bit oversize to allow a bit of shifting around. I think I had to drag the holes in the rear horizontally to allow sideways centering..... It's been a couple of years so I'm a bit fuzzy...
Also the wiring- horns, foglights, and rear license plate lights are all different and took some thought and misc grommets. It looks factory, but would never pass any kind of concours- but then again, it's a '76 with '72 bumpers so who cares?
There are also some big holes where the '76 bumper shock absorbers stuck through. When the body guy did the flares, he filled these in with steel.
Oh, and on the rear bumper, there's a tab welded to the body in the dead center. I think I saw photos of stock 70-74's, and the tab was slotted to accept the center stud coming down from the bumper pad. On mine, the body shop welded a thicker tab than stock, and with a round hole. I had to enlarge the hole, and drag it a bit to get a good fit.
Every time you drag or enlarge a hole, paint it! I used POR15, and let it go until the next weekend to harden, and then finished the assembly job.
more pics- first pic you can see holes for the bumper shocks that I was talking about. Second pic is after filling them, and you can see the tab just beneath the rear trunk lock hole. You can also see the bumper bolt holes for the new bumper. The bottom one goes in that raised pedestal, same as in the front. Last pic is the front of the car today-
