k member question
What's wrong with the k-member in the car?
Any 67-76 A-body K-member will fit, but there are several factors that make what you have the best choice.
67-72 use the same engine mounts (three different mount configurations: slanty, small block, 67-69 big block) and two different idler arm mounts (67, 68-72). The later idler arm is a better design.
73-76 use the same engine mounts in two configurations (slanty, small block). the small block can be made into a Direct Connection big block k-member fairly easily. The idler arm mount is the same 68-76, but the idler arm changed in 73 to fit the changed center link.
