Asking for a friend, really laugh

70 B body K frame, will this fit in a 75-79 B body car? Most of my peeps say no, differences in aprons? and suspension.

What say y'all?

I think the K-members changed in 73 on the B-bodies. They went to a rubber insulated K. I doubt an earlier style would bolt up.

No,it will not fit.I'm sure you are familiar with the '75-9 style K-frames as used on Magnums.The 1970 K frame is much smaller and bolts on the flat area of the frame only. Plus the upper control arm of a '70 is attached to the body/frame rail.The later isolated K frames provide the mounting points for both upper and lower control arms and strut rod as well.

pre 72 and post 73 K members are diff monsters.

Aside that, 70/72 are a bit diff from pre 69. Interchanges as a full assembly but sway bar mounts diff, so if you install a 69 K member on a 70, will need to match the 69 sway bar parts as far I know

Then, up to 72 all V8s are same K member but Hemis... and of course /6s are diff from the rest too.

since 73, /6, SB and BB are diff.

The 75-79 B body K frame first appeared in 73 or 74 and I know I pulled one of them for one of my 76s. It was also used in the 80-83 R body NYer, Newport, St. Regis and I transplanted one of those in to my 75. Recently stumbled over this handy reference:
