Axel seal help for my 62 Dodge Lancer

All those pictures i'm seeing are for a 8 3/4 rear. A 1962 lancer would have a 7 1/4 from the factory. The 7 1/4 rear did not use a tapered roller bearing with a inner and outer seal. The 7 1/4 rear used a sealed bearing, on the axle, with a seal that pressed into the axle housing. There is no seal in the bearing retainer. If I remember correctly there were either two or three different size axle bearing used on the 7 1/4, depending on year. This might also make a difference in the seal. After all these years, who knows what year rear is in the car. Best to pull a azle and measure the bearing and seal.
