Thanks guys, I have been hammering away. Not much to show but the interior is coming along, as well as the laundry list. The rear interior panels are in. I'll hopefully install the interior door panels this week.
As Burdar stated the cat whiskers fit loosely. The factory punch/pinched them in in 4 spots 2 on each end. The channel appears to be just a little wide but thats a matter of squeezing it. These are Top Cat brand from Dixie restorations. Looks like a good part. I had to cut it you can see it's long and would hit the bend in the panel. You can see the PN on the OEM part
