Brake hard line and tunnel pics needed

[marty911sc]

I'm looking for some good photos of the tunnel with the lines and front exit.

A length estimate for the rear lines?

Where is the proportioning valve?

A tips on install , back to front?

My rear hard line fitting is seized on the line and won't rotate.
It been soaking for a day or so. I had to put channel lock to break the hose loose. It's some weird size between 10-11mm.

Of course , I'd rather cut off the end first. I might replace it the whole line if I don't have the length or room to flare. The line looks really good.

I can just install the flex hose and be done with it for now. It's been down for some time.
Thanx
