Nacho is correct, those do not look long enough from the picture ... call them and get measurements.
The Mopar ones were not only listed incorrectly in their catalog, even the ones they SAY were correct were not long enough, that is why I had them routed the way I did. As I said I found an NOS set at Carlisle for cheap as it was missing the coil wire (so what).
As far as the rad, it should be on your fender tag, last number 26 or 28. It is also on your build sheet if you have it. Line 3 where it says RAD, there are 2 numbers and they are the last 2 of your radiator. Mine is 47 so it's 28 inch 3673947.
Yours according to the chart I have could be one of several depending on engine and accessories.
I am going to clear my inbox now, and I will post some new pics I just took from my phone.
Here's my fender tag. No build sheet, unless it's still in the car. There is an unknown 28 on it, no letter in front. Also an unknown E68. Interested in seeing the V5X option, black side stripes. No stripes on the car now but you can see evidence that there was at one time. Anyone have pictures of a 74 SE car with this option?
