Thanks 68Cbarge, I had forgotten that that the late B-body's t-bar crossmember also suffers from rubber isolation. I will get these as well.
Another free mod I did on those was remove the isolated torsion bar crossmember, cut out the torsion bar sockets and weld them into the frame. Converts it back to how the 72 and prior cars were. Also had to change to the older (shorter) torsion bars but wanted an upgrade from my stock SB bars anyway.
