I have gotten a few responses to my query about my cooling system repairs.
My question now is this:

Has anyone (can I) used 1.25' Copper house pipe to replace the long steel
pipes in the '85?  It looks like I could make the bends with a couple 45
degree connectors.

Any opinions on, especially, the durability of copper house pipe in this
application?  Is the pipe strong enough?  Would the soldiered joints deal
with the vibration and flex of being on a car?

I assume that there is no metalurgical reason not to use copper.

I'd like to work on this over the weekend, so opinions appreciated.
