Early 8-1/4" R&P pumpkin from an auto

Per my parts interchange book for '56-65, the diff case (ring carrier I think they mean) PN is 2070704 for the 2.96 ratio, and PN 2070706 for the 3.31 ratio. R&P PN is 2070808 for 3.31 and 2070809 for 2.93.

Differential housing PN is 2070741 on my present 3.31 x 8-1/4" R&P, and should be the same for the 2.93 x 8-1/4" R&P, and is the same one for the 8-3/4" small stem pinion, I do believe.

I can supposedly use the 8-3/4" with a change in the center thrust block but would prefer the complete 2.93 x 8-1/4"
