Default Help with B/B braided shield plug wires

I just purchased a NOS set of big block plug wires in original red white and blue Delco box There is no date code I can see and they have an eye let on one of the braded end and the other end has a slide clip .Are these correct plug wires for a '70 big block # on box is Gr.2.239 0521E9
thanks
Wes

I don't have a parts book near by to check right now, but if the spark plug end of the wires, have a clip on them, they sound like 65-66 wires. 67-74 wires have an eyelet on both ends.

The 65-66 wires ground to the spark plug barrels with a clip.

Hi Wes,
I believe gbv is right, the 70 wire braided shield would typically have an eyelet at each end.
Regards,
Alan

The old GM part number was 8912284 and the Delco short number was 458w. The clip/loop style would make these for a 1965 1966 car where the clip grounded on the spark plug heat shield.

Back in the late 80's & 90's before Lectric Limited started making the reproduction wires I found the original clips. So I used to buy the 458w wire sets cut off the loop and crimp on the clip needed to make them authentic for the 65-66 cars so it's possible that you may have a set of those wires. We would sell these at Bloomington by the case loads...

What part number is on the box... and more important, it is possible there is a date code on the box which would included a plant number and date. So look at the box closely for something like 76D2 (where the 76 was the plant D was the month and 2 the year). The only issue with the box codes would be knowing the look of the box to decide if the code was 1972 1982 1992... and so on.
