Are they missing a \r at the end of each of 150 lines?

If that's the difference, I'm not sure that there's anything you can do
about it as the sending MUA is not properly encoding the data. I.e. if
a <CRLF> vs a <LF> line terminator is significant, I think the data
should be base64 encoded. I know Outlook and maybe other Microsoft
MUAs do encode some PDFs as quoted-printable, but I suspect this is
wrong.

OTOH, if some data are quoted-printable encoded as

something=0D=0A=
or other

or equivalent, that should decode as

something\r\nor other

and if it is decoded as

something\nor other

then the decoding is wrong
