WTB Roadrunner trunk lower drip rail

[Builderguy]

I had this posted in the body/paint section but didn't get a response so maybe this is where I should have posted it. Looking for the trunk weatherstrip retainer (or drip rail I guess) as mine is rusted out and I can't make the exact shape on my break or the length. It is 55" long and the break is only 48". Yes, I could weld it but I still can't get the rounded upper shape. Someone has to make this piece as several vehicles use the same or similar piece. This car is a 73 but 68-72 should also fit, I would think. So if you have replaced yours during the restoration, please let me know where you got it. I think the original part
was #3446 530. Thanks in advance.
