Brake Lines Confusion

[ThreeQuarter]

I've searched for threads about this topic and I haven't found any that directly address my situation, so I'm reaching out for advice. Obviously I have some bending left to do to make these lines mate to the pressure switch, but here's my situation with the fit-up:

Equipment:
- 1968 C10 with original drum brakes
- All new Inline Tube SS line kit
- CPP Corvette-style master cylinder
- Original pressure switch from this drum/drum system, has two different fitting sizes

Installation details:
- Original pressure switch mounts perfectly to master cylinder with new Inline Tube lines. Mounts in same place with same orientation--small fitting forward and larger fitting to rear.
- Rear brake line at pressure switch has larger fitting
- Front brake line at pressure switch has smaller fitting

So, if I put the brake line fittings into the pressure switch ports where they naturally fit, I'll be violating the consensus advice here that says the the front brake line belongs in the rear port of the MC/pressure switch, and vice-versa.

Does that mean I need to adapt both line fittings to make the brake lines fit the correct ports, or is there something I'm missing?
