Front floor jack points

So 2x4 on the floor jack pad raising the K-member and jack stands on the LCA or on the frame rails just behind the wheel wells?

My 1973 Chassis manual just says to use a floor jack on the LCAs.

Last owned my '71 Demon in 1996 at the age of 26, so it's been awhile and a couple of bulging discs in the back since then.
