I have the Accel 8.8mm wires on my 85 and am happy with them so far.Use the ones that have a heavy gauge steel alloy conductor with fiberglass and kevlar inner core. They are gloss yellow and are quite flexible in the tight spots. Up here they run around 150 a set.You can pick them much cheaper in the states. Part number on the box is 8033

I tried the bosch platII's on my '87 and it was not happy about it. Put AC Delco's in and now we get along better.

Accel wires. Delco plugs.

Bosch plugs were OK, but not worth the $$.

.035, IIRC. I am not 100%, tho. Been a couple years. Should probably check them at the end of the season.

Talking to me? I never considered plugging them in without checking the gap first. I guess I am old school there. With the Manual in front of me, each plug was verified with the correct gap before I put them in. I don't remember the value used, but I do recall I only had to actually adjust 2 of the 8 to the correct gap size. The other six were good out of the box.
If you are looking for the number, I can look it up for you tonight.

I have Acdelco plugs along with some 7mm wires, not sure what brand ,but will be changing them soon to maybe a 8mm. The cheaper accel wires are garbage though (I know from past experience).
