Thanks. Amitiés

The 3.55 R&P set is made for the 4.11 ring gear.

The ring gear changed in 1954, when the ratio changed from 4.11 (earlier) to 3.90 (1954 and later).

The earlier 4.11 ring gear carrier will bolt right up inside the 1954 rear end.

Here is another Stovebolt.com 3.55 concersion Tech Tip. It also does not refer to the 1954/55st ring gear being different.
