looking for BTDT - MC turbo oil supply line replacement

[Livolsi, Stephane]

while the new to me 88 5ktq Avant has fairly new oil cooler lines, the line
supplying oil to the turbo bearing looks pretty bad - hard line very rusty
and braided line looking very oily.  Looking where the line is attached to
the turbo - 2 bolts (studs?) they are so rusty that they look like they will
crumble when I try to take them off.  Right now I'm inclined to not even try
and undo them, but to cut the nuts off (ouch!) with the Dremel.
Looks like I 'might' be able to do this without removing the intake, but not
sure.  that's why I'm looking for BTDT's

Anyone who has done this operation, either on car or off, please provide
your findings.

Thanks
