I'm looking for a new set of pre-formed transmission lines fr my 1968 DVC. There are several sources for these lines for 1969-70 DeVilles (and Calais, etc RWD), but not 1968.

What's the difference?

The transmission has to be the same. The only thing I can think of is the location / distance between the inlet and return fittings on the radiator. The 1968 had a low pressure no-overflow tank radiator while the 1969-70 was the first year for the sealed recovery system. The fitting locations for the transmission lines might have been slightly altered (the threads will not have been they are 1/2").

I don't see a problem with some minor additional custom bending to get them to line up with a 1968 radiator.

Am I missing something here??

Hello Mike,

I have a '67 Sedan deVille, so I cannot address your question directly.  Have you contacted Inline Tube to see if they have cooler lines?  They do brake and fuel lines, so they may have cooler lines available, or they may be able to make them using your original lines as a guide.  Have you thought about making your own cooler lines?

I make all my own lines, be it cooler, fuel or brake, and only need simple tools, which once you have, you will be set for life.

Tube cutter, Flaring tool, and a pipe bender is all you need, plus some springs to enable the bending of very sharp angles.

Bruce. >:D

PS.   There shouldn't be much difference in the tubing in your initial question, but you must remember that during model changes, some things stay the same, and whatever one wants, will always be different.

I did call inline tube. They make a set for 1961-64 and 1969-70. No 1968. Their 1969-70 set uses 3/8in tube with a 5/8 fitting.

I THINK my fittings are 1/2in with 5/16 tubing. That might be the difference. I could get around that with a couple adapters.

Or I could buy a length of coiled tubing and make my own. I do have the single and double flare tube and tube cutters, just not the bending tools, but the shop does.
