Spark plug wires sizes

[LunaticTaskbar]

Hi all,

Due to my distributor cap issues (now in the post) I am now looking at changing the spark plug wires and the spark plugs, I have heard good things about Aurora wires (http://auroraignitionwires.com)and I am considering these. However they do not seen to have a set specific for the 1974, I called and the gentleman was very helpful. He has a set he believes will fit, he gave me the dimensions. My only issue is the car is not near me to measure, Do any of you know what the correct length is for a 1.8L 1974 124 spider?

The size he suggested is:
19.5 x 3
20.5 x1
37 x1

I dont want to purchase today only to find they are the wrong length after they arrive. I can always measure tomorrow, but I kinda want to get them ordered.

Any thoughts on the length, or experience with the wires from the company?
