Welcome to the site. I have some pictures on my photobucket of my 326. It has the coil bracket mounted off the intake. If your engine is not an original fgf, it may be a bit different. It tucks up behind the air cleaner assembly. For '68 the coil bracket mounts off the throttle bracket. SO I know '67 and '68 are different. I don't know anything about '69 mounting.
It's hard to see, but if you look near the end of my "resto" photobucket, there are some shots of the engine bay.
If not, someone else may pipe in with some better pictures or info.
I used to be indecisive. Now I'm not sure.
