Trim Ring? See Trim Rings on Trans Am. Part No. 9796696

Every Rally II wheel featured a center cap ornament. Some Firebirds were delivered with the earlier style black PMD center cap orament. The original Firebird brochure shows early or prototype Firebirds with these black caps. The 1967 to 1972 Pontiac Parts Manual lists black center caps as a available "if the retainers are bent outward."

Because of the Parts manual reference, black center caps for 1970 Firebirds were probably installed on early Firebirds. Most, but not all, 1970 Firebirds were delivered with red center caps.

Part No: 9792996

Red PMD center caps are the norm for 1970 Firebirds with Rally II wheels. These center caps were used from 1970 to 1972.

Part No: 480301

The 15" Rally II was a special wheel and was created by welding another 1" ring around the a 14" wheel. Because of this the trim ring was not offerred, at least initially. The build sheet above documents a Trans Am with trim rings listed as an option, indicating that larger trim rings may have been added at some time during production. This wheel was also offerred on Catlina, Executive, and Bonneville in 1970.

A 15 inch diameter trim ring, Part No: 9796696, is listed in the 67-72 Parts Catalog as being available for 70 and 71 Pontiacs.

The conventional spare tire came with the standard steel wheel. If Rally II wheels were specified, a fifth Rally II wheel was supplied with the spare, unless the Space Saver Spare (UPC N65) was ordered.
