Tight Handbrake

I'm having the same issue on my new to me '64 vert. My front cable is frozen and I cant find a listing for it.
The earliest front cable listed says it's for 67 & up, Raybestos # BCA92319. Conduit length 40" overall length 91".
I just came inside from under the car, I'll try to measure it tomorrow.
I have new rear & intermediate cables.
Anyone know if this later listing will fit the earlier car?
Or have a part# / source for the early one?
OK so digging deeper (looking at pictures on Rock Auto) it appears the entire '67 & up cable system is different.
So I need a source for the '64-'66 front brake cable.
Tomorrow I'll attempt to remove it and get it free'd up. :(
Like grouchyandugly the nut is not coming loose from the adjustor, it has been sprayed. But since I have the new intermediate cable I'll just cut the old one and see if I can soak the entire front cable assembly in oil.
