Our Readers' Ford Mustang Technical Questions
I know that the original distributor for a '69-'70 Boss 302 was an Autolite unit stamped with part number C9ZF-12127-E, with C8OF-12131-A cast on the distributor housing shaft. There has been some discussion about the primary wire hole, whether it should be close to the vacuum advance or near the center of the distributor housing. Did Autolite produce Boss 302 distributors with primary wire holes in two different locations?
Los Angeles, CA
The correct location for the primary wire opening is near the vacuum advance unit. The other location is for single point distributors. More than likely, you've seen single point units that have been converted to dual point for Boss 302s.
The C9ZF-12127-E is actually an engineering number.
Early Steering Columns
I read previously that you own a '65 fastback with Raven Black exterior and red interior. I own a '65 fastback, built October 8, 1965, with the same color scheme and my question concerns the steering column. I am curious as to why my steering column is black. I have looked at it very closely and do not see any evidence of a repaint and the original mounting bolts do not appear to have been loosened or tampered with. I can only assume that it received a black steering column because it is an extremely early fastback. My Mustang also has the woodgrain steering wheel, which I guess was included with my car's original Special Handling Package.

My Hi-Po fastback is a '66 model. However, the steering column on a '65 would typically be red as well. The woodgrain steering wheel was an option and not related to the suspension package.
I am restoring a '70 fastback which was a basket case when I bought it. I don't know if the bucket seats are original to the car. Is there a difference between '69 and '70 Mustang seat frames? How can I tell what I have so I can order the correct upholstery?
Via the Internet
The best way to differentiate '69 seats from '70 seats is the location of the seat back release handle. The '69 version is “high” in the middle of the seat back on the exterior side. The '70 version is “low,” near the bottom of the seat (see photo).
Engine Bay Details
I am in the beginning stages of restoring my '66 hardtop with the 289 two-barrel engine. What shade of black should I use for the engine compartment and which decals from the engine decal kit should I apply?
Sydney, Nova Scotia
We use PPG DP90LF black primer for protection of the bare metal, then use PPG DDL-9423 for the correct semi-gloss black finish. I would recommend a '65 Mustang decal kit from ECS Automotive Concepts or Jim Osborn Reproductions. Most major Mustang vendors carry both. As for which decals are correct for your car, I would need to know the production date and assembly plant.
Pony Interior Release
I have a '65 Mustang hardtop that my father purchased new from a dealer in Dallas. I went with him to buy the Mustang, which was so new that the dealer had not had the opportunity to prep it. The car has been in the family ever since. I recently read that the Pony interior was not available until March 1965. The build date on my car, 23A, indicates that it was built on January 23, 1965. I was only six-and-a-half when my father got the Mustang, but I clearly remember how cool it was that there were horses in the upholstery. Do you have any information about the release of the Pony interior prior to March?
The 23rd of January is only five weeks before March, so I would not be concerned. The interior code on the original door tag will confirm your Pony interior. Many of the published dates for items like the Pony interior were scheduled release dates, not necessarily the actual release dates.
