Will Posi caddy 65-67 fit ?

I have a 65 Electra with a non posi dif. I can get a 65-67 caddy posi that look simular, but i'm not sure. Who can help me? I only have 1 picture

Please put your name in your signature, we are all here on a friendly first name base :TU:

And don't forget to introduce yourself (and your Buick) in the Wet behind the ears?? section of the board :Smarty:


And now for your question:

Both cars are C-bodies, both are 31 splines axles with a 4-link set-up, this will be a bolt-on conversion.

 

Control arm locations appear generally right-maybe will fit-maybe not=measure everything and compare first-good luck and let us know

 

thanks guys for your answers.
@Bad Boattail:
will the caddy pumpkin fit at my buick rear end or do have to change the complete rear end?

 

I have both a 66 caddy and 65 Wildcat- I will try to look and see but my opinion is negative at this time.
What are you looking for - more gear, POSI, or service replacement?

 

i want a posi and i don't like my 3,42 gear. I can get a caddy rear end with a posi with a 2,94 gear.

 

Pretty sure it is going to be swap the whole rear. Do not believe the third meember bolt pattern will be the same. Sorry. Jim
