Radial Tires

I have a tire option question. Did Ford offer a radial tire for the '67 Mustang? If so, what is the correct tire size?

Radial tires were available as an option for the '67 Mustang. I'm not sure if they were available right at introduction but they do show up as an option on the April 1967 vehicle order form. The supplement pictured above is dated January 1967. This supplemental flyer was added to the salesmen dealer facts book for reference.

The size listed on both forms is 7.35x14 (185Rx14). Radial tires were not a popular option for '67 Mustangs but they were available according to the documents.

Underhood Black

There seems to be a lot of confusion about what type of underhood black is correct for a '70 Boss 302. What do you prefer? I do not want to use a spray bomb.

There are a lot of opinions on this topic. Since 1980, I have used only PPG DDL 9423 as a top coat. In my opinion, it has the best color, texture, and semi-gloss sheen. To me, many of the low-gloss black formulas look gray. The DDL is “black.” It's also lacquer-based with minimal mil thickness so you don't lose the stamping marks in the metal. We use DP90 LF as an epoxy protection under the DDL. This combination has held up very well for us over the years.

I have a '69 Boss 302 that is being restored. I need to know the correct strut rod bushing kit for this car. I need to find the real deal, not service replacement parts. I have not been able to get a straight answer or how to identify the correct stuff. Please include photos if you can.

Great question! It seems there is a lot of confusion about correct '69 Boss 302 strut kits. The Ford part number is C9ZZ-3A187-A. This kit was replaced by D0OZ-3A187-B in 1972.

The unique part of the C9ZZ kit is the front washer. As you can see in the photos, the washer is blue with a circled logo stamped in it. The rear washer is a C8OA-3A141-B, which is the same as the standard '69 Mustang. The bushings are also standard '69 Mustang parts, C8OA-3A140-B and C8OA-3A225-A. Until recently, these bushings were nearly impossible to find as NOS or good used. The correct C0ZA-3A142-A blue washer is very similar to the standard '69 Mustang part but is thicker due to the F60x15 tires on the Boss 302.
