Old chrome Buick Nailhead water neck housing or water pipe
or crossover whatever you want to call it. Not sure on exact years it fits measurements on mounting holes is approximately 12 1/8 on top and 11 3/8 on bottom center to center. Still has some what of a shine with plenty of imperfections in the chrome. Water neck was chromed too but it's all but gone looks to be aluminum but it's obviously seen better days.Free shipping in the lower 48 States. Check my other items.
