1969 Boss 302 & 1971-1973 Mustangs - Resto Roundup
Concours Expert Bob Perkins Handles Your Restoration Questions
Spoiler HardwareI have a question about the factory-installed '69 rear deck spoiler for the Boss 302. This question also surfaced on the Boss 302 web site (www.boss302.com). What is the correct hardware for mounting the spoiler to the decklid? Is there a larger hole on the bottom of the decklid for the insertion of a spacer? If you can include a picture, I'm sure many Boss owners will appreciate it. Any additional information will be appreciated.Frank MurrayVia the Internet
The '69 Boss 302 rear deck spoiler is bolted from the bottom of the decklid. Unlike the '70, which has studs on the pedestals, the '69 uses four bolts marked "Tritonium" on the head with loose washers and a spacer to prevent distortion of the decklid when installed. Shown is a picture of the underside of the decklid, along with a photo of the bolt, washer, and spacer.
Also shown are the three different style gaskets used on '69-'73 rear deck spoilers. The correct gaskets for '69, '70, and '71-'73 Mustangs is a common topic of discussion at many car shows. There are actually three different sets of gaskets used for the '69-'73 Mustang rear deck spoiler. The '69 Boss 302 used a very generic-type gasket with no Ford logo or engineering part number. Both left and right are symmetrical. The '70 gaskets are marked left and right with Ford engineering numbers: D0ZB-6344229-B LH and D0ZB-6344228-B RH. The '71-'73 gaskets are also marked left with D1ZB-6344229-AA, and right with D1ZB-6344228-AA. Note in the pictures, the '71-'73 gaskets are much thinner than the '69 and '70. The hole spacing is also different on '71-'73. Correct original spoiler gaskets are a rare find today.
Fender Date CodeI just purchased an N.O.S. '68 right fender, still in red primer. About halfway up the lip where the fender attaches to the body is a series of numbers: 126D3. A friend says the fender was made in 1973. The shipping label says November 1971. Can you shed some light?Cal SolinskiKnoxville, TN
The date code indicates December 6 at the Dearborn stamping plant, third shift. It is not possible to determine the year the fender was made by the date code, only the month, day, and shift.
Suspension DetailsI recently called the Mustang Club of America office for some information about suspension details for my '70 Boss 302, and they suggested I contact you. The MCA rulebook provides some details on the front suspension, but I'm looking for extra details. In looking at the trailered concours or thoroughbred class guidelines for front suspension detailing, what is the correct finish for upper and lower control arms, tie rods, tie-rod connectors, idler arm, pitman arm, and power steering box? Are there any paint identification codes for the above parts? Also, I need information for the strut rods, strut rod washer, and insulator parts.Keith SneiderGrand Island, NY
The correct finish for the upper control arms, idler arm, pitman arm, steering box, strut rods, strut-rod washers, drag link, tie rods, and tie-rod connectors is bare metal. The upper control arms, strut rod, and strut washers are a shiny stamped-steel finish. The idler arm, pitman arm, drag link, and steering box housing are bare cast finish with some machined surfaces that are also shiny in appearance. The top of the steering box is often blacked out with semigloss black as part of the undercarriage black out. This was usually done with a brush application. The lower control arms were dipped in semigloss black, but the ball joint end was left natural. Usually about 3 to 4 inches on the end is bare, shiny metal. The tie rods and connectors are either shiny bare metal or a dark blue-black finish, depending on whether the heat-treating process was oil or water-cooled. Most '70s were the dark finish, while most '67-'69s were shiny bare steel. The idler arm, pitman arm, and drag link had pink paint codes for manual steering and yellow for power steering. The front strut rod washers had a yellow dab for most '70 Mustangs; '69 Boss 302s and very early '70s were blue. The '69 and '70 Boss used different strut-rod kits.
A detailed undercarriage and suspension-detail article is in the works for a future issue of Mustang Monthly.
