Exactly what lines are you needing? Under hood main lines?

As in the compressor to plenum box? Dvrs side 2 lines?

If the metal ends of the hose are okay, any good A/C shop can make new lines for you. They cut the metal pipe off of the hose and braze it to new fittings that are designed to be brazed to.
I did this when I had new lines made for the Sanden conversion I did.

Original Air has them I believe. I just put my second Sanden compressor conversion kit on yesterday, only way to go, I think you can buy stock style hoses from them if that's all you need.

That looks like a really nice kit. I might go that route as I was wondering about the best way to upgrade my system to run 134a.

It's the only way to go, I can do the whole thing in an easy half day , but I have the crimper tool . you have to crimps to make.

I did my high boy a couple years ago and I love it so much I just did my '79 last week. it solves a lot of problems and it works better than the original set up ever did.

About the time I think I've decided to give up on my AC, this comes up ... ... keep it up and you gonna make me pull that trigger yet. Should wait to after the new years ... to be ready for Spring.

Besides the kit and liquid hose maybe, I see it includes reciever drier ... did you maybe just cflush the condenser and / or evaporater?

Yes I ran a can of the flush stuff through. unless your old compressor put metal through the system it's probably not needed but they recommend it.

The compressor comes with the proper charge of oil to you just bolt it on and charge it with R134a and drive. at the cost of R12 now days it's a no brainer to go this route, this and radial tires are the 2 best upgrades you can make as far as I'm concerned.

My compressor just leaks out the freon from the seals, it never blew up, etc. I just took the belt off a couple years ago. I have a 2001 Mercury, had it since new, 94,000 miles, it has yet to be recharged, AC will almost let a body hang meat. Come to think on it, my '95 Thunderbird has cold air too, it's OEM too.
I've got a couple others, but they are newer, bought extra R-134A on a spercial store promo about 10 years ago, never have needed the first can.

The '77 has been charged at least once after getting "weak" of R12, now again it's really low, last I looked lots of bubbles so something was in there when I took the belt off.

I went through a couple rebuilt York compressors before I put the Sanden on. if you can but a good piston compressor anymore I can't find one. not only does this new set up work better but it takes less power and no more hammering vibration under the hood. I kind of wish I had the looks of the original compressor but that's the only thing I mist about it.

The E-Vap(?) valve, right there by the fire wall. Did you have to do anything with it? The kit looks great and semi cheap, I am just worried about the Valve. lot of stuff to remove to replace it.

Ya, easy to get to? I replaced the squirrel cage and the heater radiator years ago, little bit of work to get to it.

The expansion valve isn't bad at all . yeah the core and fan are a biatch I'm dreading that when the time comes.

440 six pack I am with you. Like the idea of the old compressor. Besides I have a few cans of r12 laying around the garage. Hopefully have my truck back together in 23 and I will give it a try. It hasn’t had anything in the system since about 1990 but when I disconnected things there was some residual pressure. No Freon just temperature changes with outside air. So it would appear the system was sealed.
