Checking on EBay they have new filler necks. It may be best to buy a new one then you know what you have. I bought a 74 back in 74 great truck kept it 11 years no real problems other than rust living in the mid west you have that anim_25
Yup I have minor rust which is not bad for 40 years of mn winters. I might switch out the neck if this last place doesn't have it. For some reason my phone won't upload images. It's frustrating. I might say this 74 is bringing me bad luck. Lol I am not giving up though! Only thing left is weld some inserts on the back arches and paint! Thanks for your ideas. I'll post some pictures when I can sit at my desktop.
