Grand Marquis Plug Wires
I have been calling Ford dealerships to try to track down a set of original Motorcraft spark plug wires that fit my 1984 Mercury Grand Marquis LS with the 302 V-8 engine. I would like to use the factory wires, but the only information I have discovered so far is that the wires are different depending on whether my Mercury has EEC IV or not. Can you offer any help with what EEC IV is and if I have it in this car? I still need to locate the correct wires, based on the answer to this question. Tune-up time is approaching quickly.

The EEC IV or thick-film ignition system can easily be identified by looking at your distributor. The electronic control module for this system is made of blue or gray plastic and is bolted to the front of the distributor. A harness with four wires in it attaches from this module to the coil and Powertrain Control Module. Your vehicle, based on your VIN, would not have used EEC IV unless someone added it after purchase. Your original Ford wires should be # E8PZ-12259F and the Motorcraft number is WR-3946C. There is only one set with the original Ford part number available from a dealer in Texas listed below. The Motorcraft set is available online from Summit Racing or Rock Auto. Both O’Reilly’s and Auto Zone stores in your area should be able to order them for you as well using that same Motorcraft part number.

1952 Ford Customline Trim Pieces
I am in the process of restoring a 1952 Ford Customline, and I am having trouble locating the parking lamp lenses and headlamp rings. All the catalogs I’ve looked at list 1949, 1950, 1951, 1953, etc. But they don’t have 1952. Any idea where I can locate these parts?

The 1952 lenses were specific to that year and were clear with three spokes around the perimeter. They were sunk into the fender at the ends of the grille bar. They are available from Concurs Auto Parts or Early Ford Store of California as part# FAA-13208. The mounting gasket is also listed as FAA-13211A. Concours has the headlamp retaining rings as part# 13015, which fits 1949-’57 passenger cars.

El Camino Vapor Canister
I’m looking for a vapor canister for a 1987 Chevrolet El Camino with a V-8 engine. I believe the original GM part number was 17075849. Thanks in advance for any help you can provide.
– Phil White, via email
The GM number you provided is a supersession of the number 17075824, which was discontinued in 1987. But guess what? That number was also superseded in 1993 by 17064622, which was the number used in earlier years for the 5-liter engine. We were able to locate the number you requested from a GM supplier, Craig Motors in California. They also showed one of the other superseded numbers, but we suspect they have just the one with both part numbers referenced. Delco sold the same 17064622 5-liter unit as number 215-22, which is available from Hall Chevrolet in Virginia.

Camaro V-6 Exhaust Y-Pipe
I own a 1991 Camaro RS with a 3.1 V-6 automatic, and I’m looking for new exhaust manifold Y-pipe. My local parts store doesn’t list one for a 3.1 V-6 and doesn’t clarify if the one listed for the earlier 2.8-liter will fit this car. The other one shown is for a 4.3 V-6 with a manual transmission. How much difference is there between a 4.3 and a 3.1? Love your column, it’s a great addition to Hemmings.

The exhaust components for the 4.3-liter V-6 tend to be more like those used on the V-8s rather than the 2.8 or 3.1 V-6s. We did find that Walker produced the pipe you need, and it fit both the 1985-’89 Camaro/Firebird 2.8 as well as the 1990-’92 3.1 F-bodies. Their part number was 40442, but it has been discontinued. The exhaust donut gaskets for the 2.8 were sintered metal whereas the 3.1 gaskets were GraFoil, but the exhaust pipe is the same unit. AP Exhaust made an equivalent pipe, listed as part number 94925; however, we were unable to locate one. We suggest you contact Trans Am Creations USA and ask them to check if a good used unit is available. Hemmings advertiser Martin Johnson may also be of assistance; while his main focus is pre-1979, he may have the bend patterns for the Walker or AP number to replicate it.
