Great rear for a hot rod, the Dana 44 is an 8.5 ring gear so it's strong. 4.09 ratio with the sturdy Power loc, not the crappy "trash loc". Ring gear looks awesome, NO rust inside. OAL is 62. Flange to flange is about 581/2. Leaf perch center to center is 40. Hadn't had the drums off yet but they may be OK, truck had 85K on it when retired. Can bring to the Spring Jefferson swap.
