No they are not made. You have to purchase the 30 spline axles and the 30 spline side spider gears. That is unless you are going with a posi.

The '55-'62 1/2 ton differentials are the Eaton HO32/33 which is totally different than the truck 12 bolt and really not much in the way of aftermarket support for them. To my knowledge they are 62" wide just as the '63 to early '70 truck 12 bolts are.

Then I decided I better upgrade the Posi so I went to Quick Performance and bought everything from hub to hub make it happen: http://www.quickperformance.com/GM-1...-12T_c_54.html
But I don't think the wider rear end parts on the 61 will be available.
