A body K member
Don't use the 67 K-Member. You were warned here, They did away with that style idler arm for a reason. Without a through bolt they were a safety issue . Look for a through bolt idler style. 68-72 . The 73-76 spool mount style were great until they made interlocking biscuit style replacement mounts. Now they are just a used when you can't get the correct one you need.
There are also lower control arm supports on all cars that came with the stiffer torsion bars from 1970 and newer. These are identified by a washer welded to the front. They did this due to problems with the control arm pins busting the k-member with the stiffer bars and stabilizer bar. First picture is a standard style and second picture is Heavy duty. I also included some side by side pics of the biscuit and spool mount style for your reference. As you can see the spool type makes it tight for some headers clearance. The choice of headers can make a difference.
