69 nova rearend question

Will a 75 omega rear fit as a direct bolt in 69 nova .

Dimensions are common, but there might be a few differences. All 75 X-body diffs had multileaf mounts, 69s had single except for the SS. You can change springs or I think there are spacers to adapt. Also the ujoint might be different. There is a break somewhere in the 70s on ujoint size used, not sure what the year, but I put a 79 T/A rear under my 71 and it used a bigger ujoint. There is a readily available ujoint will adapt the sizes, 3022X IIRC.
