What other year full size rear end is a duplicate for a 1970 Catalina rear end? Are the rear ends the same let's say 1967-1970? Are the mounting brackets and locations the same? Thanks in advance.

'70 model Pontiac B series is the same as '69. '68 is a different housing.

Iv'e got a nice 2:93 posi from a 50,000 mile 1970 Bonneville if your interested, I will sell it for a fair price I paid $475 plus 175 freight from Frank's Pontiac last summer and after I got it I replaced the seals, cleaned and painted it.
