72 door panels on earlier door

[jctweedt]

I have a 67-71 door on my drivers side with a 72 panel. It was loose so I pulled it assuming it just needed new clips, not realizing the older door panels mounted up differently. Any suggestions on mounting this panel so it isn't loose along the bottom? I'll drill out the holes up top to line up with the clips on the panel, but I'm not too sure what to do about the bottom of the panel. I could throw in the earlier style square clips, use screws and drill into the door panel itself, but I'm not sure if that would look like crap or if there's a better option...
