k member

There are differences in the ones Moparparts listed as well. Naturally, engine size differences need to be addressed but even so, some years have unique features. If yours is a V8 but not a Hemi, the '70-74 E-body K-members will work as well as the '71-2 B-body ones with the same engine restrictions. The '74 K-member has some extra motor mount interlock brackets but will still interchange....it just looks a little different. Some models, like 440 magnum and 6bbl cars, have an extra little skid plate welded to the bottom for oil pan protection. There is an early and late K-member for the '66-70 B-bodies too. Mostly the difference has to do with the sway bar mounting. As for lower control arms, your will interchange with '62-72 Bodies and '70-74 E-bodies if you don't have a sway bar. If you have the factory sway bar, the interchange is '70-4 E-body and '70-2 B-body.
