Wrong axle length, green bearing fix?

8 1/4 inch rear ends didn't appear until 1973, right?

The Chrysler 8-1/4" rear axle was introduced during the 1969 model production run B-bodies and C-bodies with 318 engines. The 8-1/4" rear axle is a Salisbury type assembly and differs from the banjo type 8-1/4" rear axle used in 1957 to 1962.

Due to the late introduction in the 1969 production run, the 8-1/4" rear axle is not included in the 1969 service manuals. Some information is in the 1969 Service Highlights and the 1970 service manual is suitable for service operations on the axle.

The axle continued in production and expanded in use over the model lines. Additional gear ratios and Sure-Grip was later added to the axle offerings. It was available after 1969 in the following applications depending on other equipment and duty ratings:
- 1970-1979 B-bodies
- 1970-1978 C-bodies
- 1973-1976 A-bodies
- 1976-1980 F-bodies
- 1980-1983 J-bodies
- 1978-1988 M-bodies
- 1979-1981 R-bodies (8-1/4" axle standard)
- 1971-later B-series vans
- 1972-2000s D/W-100 and D/W-150 series trucks (it was more broadly available after 1974 when the larger 9-1/4" axle was introduced to replace the 8-3/4" axle)
- 1975-1993 AD/AW series sport utility vehicles (Ramcharger, US models)
- 1975-1980 PD/PW series sport utility vehicles (Trailduster)
