Brake line question, oh yea itsa dumb

[sapper]

I know the answer i think but here goes, while working with dodge calipers for my 60 i drilled out the brake lines i have to fit the 7/16th banjo bolt for dodge, well now i have GM calipers on it and of course the banjo is smaller, do i need new brake lines or will the washers hold without leaking? TIA

Get new lines. OR use an older set of calipers. Same things, but 7/16" input.
