1959 El Camino Rear end

#1
I came across a 59 El Camino with what looked like an original big block setup. It had the shorter fan shroud bolted to the original radiator engine was not a 348 but it was a more modern big block. Does anyone know what type of rear ends came in those trucks? The rear end that it had did not have any bolts on the back like the 10 or 12 bolts you see on other trucks. It did look a lot beefier and was somewhat oval shaped. Google was no help so I ask the experts.

The 59 Elco had the same rear end as your 59 Impala,Jackie.The gearing might have been different,but that's about it in stock form.Look at yours,then compare.That rear could have been changed to an Olds/Pontiac or maybe even a Ford 9inch ,but we'd need pictures to be sure.

Thanks Don, I wanted to take some pictures but it was some old parts cars (3) in the weeds and I was scared of getting bit by something. They all had the same rear so I am thinking it was stock?

What I saw was no bolts at all on the back just the drain plug. The axel tubes were a lot thicker and the pumpkin was bigger and more oval. It won't be soon but I'll try for a picture next time I go there.

The answer to both is yes.The OLDS/Pontiac rear is heavier and stronger than a 9in,but is older and harder to find parts for.If either rear was swapped into that truck,it likely has a posi in it.Why would anyone go to the work and expense to install a big block,and upgrade the rear and not run a "posi" of some type?

They're both stockers,the same basic thing that you have now.They might have a little deeper gear ratios than you currently have,but that will be it.
