Military Spark plug wires

[bl5211a]

Hello, I have 3 NOS spark plug wires that are approx 34 inches long. I am not sure what application they are for? They are constructed the same as the wires for the M38a1/M170, but 5" longer.

Can anyone use these?

From the post two down on this page:

As for ID'g plug wires many will interchange or work but original factory installations differed significantly between the M37, M38, M38A1/M170, and the M151.

M38:

7528173 Cyl # 1 23 3/4" long.
7528174 Cyl's # 2, 3, & 4 19 3/4" long.

Both ends are 90 deg elbows.



M38A1/M170:

8328449 4 Ea. 29" long.

Both ends straight.



M37:

Early engines up to eng sn 25519:

7528172 - 6 Ea. 24"

Eng sn's 25519 & up:

8328040 - 5 Ea. 24"
8328039 (superceded by 8741873) - 1 Ea. #1 cyl 22"

All three above are 90 deg. elbow one end and straight the other end.



M151 Series:

11660569-1 2 Ea. #3 & 4 cyl's.
11660569-2 1 Ea. #2 cyl.
11660569-3 1 Ea. #1 cyl.

As you can see below these are very short running 11" to 16".



M715:

11641027-1 Cyl # 1 18.5"
11641027-2 Cyl # 2 20"
11641027-3 Cyl # 3 22"
11641027-4 Cyl # 4 24"
11641027-5 Cyl # 5 29"
11641027-6 Cyl # 6 31.5"

All cable ends are straight.



Which of these wires is closest to the three you have?
