So I have these smog manifolds for well over a decade, probably bought at a swap meet. Original smog tubes on them, never been apart (till now) and original looking rust. Just getting around to cleaning them and found a crack, so disappointed.
Drivers side rear bolt hole, is it fixable? should I fix it? Crack does not appear to go into the bolt head surface. I have to clean the other and see if that has any issues
Any opinions? thx
