New SS Lines if replacing Clutch Master and slave??

I already did, but you don't need to go to Hall for that. You can just make it up out of any brand of braided metallic hoses and fittings.

You can use a -3 or -4 hose on it. I used -4 Aeroquip brand with the Teflon lining like you would use on the flexible brake lines.

SS clutch hard lines would just be cosmetic if your existing hard lines are in good shape. A SS flex line would be a good upgrade.

If you want to have some fun, get a tubing bender, flare tool, some mild steel line, fittings, and make your own. Bending and flaring tough SS hardline is a bear.

Same here.
I made my own braided stainless lines using Earls -4 speed seal hose, (teflon lined).
From the master cylinder all the way to the slave cylinder.
Used Earls stainless hose ends at each end.

To be specific, the stock brass junction on the lower rear subframe has a metric hose bib for the infamous red plastic line going up to the slave cylinder. Coincidently, that hose bib's metric thread is a direct swap for a double-dash-4 AN fitting (with an o-ring on the end going into the junction). Then, you can run any dash-4 AN braided-stainless hose up to the slave cylinder. Because slaves can be threaded several different ways, you will need to search out a compatible dash-4 AN fitting to thread into your slave cylinder; a 1/8-SAE pipe to dash-4 AN is one possiblity. Summit Racing sells a cheap braided-steel clutch kit- not specifically for Panteas- that's been successfully used just recently.
