You read it, I’m replumbing the deleted rear heater, with the pipes and heater currently still in place. However, I have yet to find clear pictures of the firewall showing me where everything is supposed to go, I would graciously accept any crumbs someone has to offer. I also don’t know why it was deleted in the first place, the pipes look rusty on the outside but I didn’t feel any obvious bulges or leaky points. I would like to use the same pipes and/or core as long as I can find a way to “pressure?” test them, has anyone accomplished this feat?
