Early A K-member help

Here are some pics of different K members. First pic is 62-65 B body V-8 ( to my knowledge, as I got it from a property clean out and was told that's what it is ). Second pic is 62 Dart slant six K member, I parted this car. B body K members
are appox. 33.5" O.C. for frame rail mounting. Last pic is 64 A body at 31.5 O.C. for frame rail mounting.
All this stuff is for sale if anybody is interested.
