Is this a Pontiac rear end?

Was told this was a Pontiac or Olds rear end from '57. Any help on the ID appreciated. Rod in Escondido

 

Nope, could be a Dana?

 

Nope!

Pontiac looks similar by design to a Ford 9".

 

Could also be a British built version of a dana like used in the 50s Jags and MGBs.

 

Car was assembled in 1958 through 1959, so it wouldn't be an MGB. Has to be earlier than 58. Sure appreciate the comments. Another JJ mystery to be solved.

 

Probably a dana 40 or 44. The 44 was used in lots of Fords in the early-mid 50s, such as pickups and wagons and early T birds

 

Just found an article on that car and while it says little about the axle, it does say the transmission was pirated from a C Jag.

 

Correct. The C jag gearbox is long gone, as is the Hemi, but the diff is still in the car. Always thought it was a Pontiac, but now I'm researching it and I'm thinking I was incorrect (for 40 years). Rod

 

that's not really the side we need to see to determin its origin.

 

That is the side we need to see to determine that it's not from a Pontiac earlier than 1964.

 

Here's a Jag XK140 rear for comparison. Looks the same.

 

Thank you, LS&A... it does look like the XK unit. My, My. Very surprising, but it does make some logical sense. If the drive train componants were selected at the same time, then it may be Jaguar. JJ is a wonderful resourse.

im betting dana 44,,,

 

Salisbury 2HA or 4HA is the British version.

 

Probably the british one, if it's in a little sporty car. They're not very wide, are they?

 

Pretty much all itty bitty.

Here's the car in question, even has knock off wires.




Just found another hitch in this other article following it though. Says the axle is Lincoln. Could be either but the U-joint looks Jag to me?





1950 Merc. Dana 41/44?

 

They often have the model number cast on the outside of the housing, perhaps next to the axle tube on the back of the flange near the cover.
