Buying Ignition Parts for a 1970 Fargo W100 Pickup
On this vehicle, the ignition system delivers spark at the right moment — plugs, coils, wires, distributors and ignition modules.
- Match the engine first. Some ignition parts fit every engine; others are engine-specific. Each row shows which engine(s) it fits.
- Read the notes on each row for position, trim and spec qualifiers before you order.
- Where labor overlaps, replace plugs and wires (or coil boots) as a set — one weak cylinder makes the whole set feel bad.
- Cross-reference the manufacturer part number against your old part or a service-manual listing.

Notes on this page include pre-set gaps of 0.032", 0.033", 0.035" and 0.039". Still verify against spec — even “pre-gapped” plugs should be checked before they go in.

What do the market flags (US, CA, MX) on each part mean?

How do I make sure a part fits my 1970 Fargo W100 Pickup?
