Default S4 to '84 rear brake swap question - which brake lines?

Good morning - quick question on swapping S4 rear brakes to an '84.

Do I now need to use the brake lines that are correct for the S4?

Not sure what the difference(s) are between the lines that the '84 would use vs the ones specified for the S4.

Thanks!

OK - I'll answer my own question.

No, not the same. Rear brake lines on the S4 that mate to the caliper are a different size than the stock rear lines on an '84.

This is based on pulling the S4 rear caliper and offering it up to the '84 rear brake lines.

My solution was to use SS brake lines. Worked well on `78 car to S4 caliper
