I have a 1990 Brougham 350 and am in the process of choosing the parts for a spring tuneup. I'd like to stick with ACDelco, but rockauto.com is listing two different wire sets, and am not sure which I am supposed to be using....


ACDELCO Part # 708S {replaces 12073969 #12073969, 19154579}
Spark Plug Wire Kit 5 WIRES W/BOTH ENDS 90 DEG, 3 WIRES W/ONE END 90 DEG AND ONE END STRAIGHT

ACDELCO Part # 608B More Info {replaces 12043726 #12043726, 19172234}
Spark Plug Wire Kit w/ARMORED BODY EQUIPMENT(B05); ONE END 90 DEG, ONE END STRAIGHT


Anyone know how to choose which to purchase?

Looks like the first part describes the 8 wires going from the distributor to the individual spark plugs. The second one is probably the main wire going from the ignitor to the middle of the distributor. For a thorough tuneup I guess you should replace both - though that does make me wonder if I rememered to replace the main wire when I did my wires...
