69 camaro - GM gas tank vs repo

[Mr.Nickey Nova]

Ed,
That looks like a repop tank to me.The tank it self looks the same as a NOS,but the big difference is the filler neck.I tried a repop tank on my 69 Z once,which wouldn't fit good due to the filler neck being up to high.So i returned it and went with the original tank after i had it cleaned out and sealed inside due to rust.It's all about the filler neck.Nothing like the original stuff...
