After I finished the WP , rad hoses and T stat, the tranny cooler lines failed on the maiden voyage. Fine , at least all of this happened locally.

Anyway they don't make pre bent tubes for the old vans. Pickup trucks and muscle cars sure no prob.

Hmm, C series Chevy : 88 -92 : 5.7L with 700R 4 & similar radiator , lets give those a try.

Looks like a perfect match except my upper line is lower than on the C series at the radiator.

Didn't want to get involved bending my own lines or double flaring one end. Napa has lines with flared ends but the length is hit or miss.
Longest they have is 60" and these are around 70" and I would have had to piece two together.

Remove the old lines and match them up for fit.

Classic Tube : $ 45 for the pair, $ 85 for SS ( I don't need that ).

They weren't even close, I threw in the towel.

Had the garage come with the tow truck and while you are at it change the tranny fluid and filter, dump the rear axle gear oil and add the LSD additive, change the engine oil and filter and grease the front end. Replace the 20 year old hoses on my tranny cooler too.

He did a Redneck job on the cooler lines, not a prob. Used Nickel / Copper lines, they bend easily and are more rust resistant.

$ 500 including the tow, a bargain.

350 miles round trip and my van was Great ! Not too shabby for 178 K mileage.

Have to order a few patch panels for the rear sheetmetal, it has to look respectable. I'm driving a classic and it must look nice. People make fun of me and make stupid comments like " I'm surprised you can keep it on the road anymore " ......  Mines been paid for since 1993, how much does your vehicle cost you per month including insurance ?

 I wondered about that. I couldn't see them being close. But, who knows. Wait and see. But, it's done now. One of my most disliked jobs, bending steel lined to fit.

Given my druthers Mastercool has a nice double flare machine for $ 325. What my mechanic has.

http://www.mastercool.com/pages/flaring_tools.html

If you don't have the good tool don't waste your time. I have KD flare tool ( $ 60 ) but they are marginal at best.

Hard to justify the purchase at this point. But I like good tools, keep some tubing in stock, etc.

Never seen a good tool I didn't want to own.

 Yep, nice to have the good stuff. But you have to rationalise buying it. An occasional use is tough to rationalise. But it sure would work nice. Then look at the cost of having it done vs buying the tool, the tubing than doing it yourself.

 But then if you're a tool junkie, it's a no-brainer.

I'm a tool junkie but I'm running out of room for more.

I've read if use a tubing cutter that hardens the steel and then it cracks easily when you flare it.

Should use a cutoff wheel, then you should have a disc sander machine to square up the ends. Have to deburr the tube end inside and out before you start the flare operation.

All part of making your own double flared lines.

Be nice to have the pro tool.

Or get pre bent lines from Inline Tube : http://www.inlinetube.com/

All about supply and demand for the high build number or in demand resto cars, or later model stuff.

I did well on my brake lines with Napa pre flared lines in various length increments, some of them were the perfect length.

After I pulled the tubes and measured them with a string they were 58" & 62", I could have made the 60" lines work easily but I had enough at that point.
