Rear axle flange patterns: is GM 14 bolt drilled on same bolt circle as GM Dana 60 ? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Is the 73+ GM 14 bolt axle flange drilled on the same bolt circle pattern as the 68-72 GM (& 73+ Jeep J20) Dana 60 axle flange ? I know the 14 bolt only uses 4 bolts to hold the backing plate on, where the Dana 60 uses 7 bolts on the backing plate, but it looks like 4 of those 7 bolts on the D60 are identical to the 14 bolt.

Wondering if my 14 bolt rear disc brackets (with 4 holes) will line up and bolt onto a GM Dana 60 (using 4 of the 7 holes).

I checked the 1972 K2500 Dana 60 I have, and compared it to the big drum FF corp 14 that I have as well.

The bolts in the square pattern that the 14bolt has are 3 1/2" apart, and if you measure the bolt pattern on the D60 in a 4 bolt pattern like the 14bolt. The D60 is also 3 1/2" apart.
