Some one has probably removed the original suspension for a conversion to a strut suspension. The original suspension was hydropneumatic struts, 5.5x14” Fuchs wheels and 185-85x14 tires; there were other parts I can't remember. This suspension on every 911E of the period (’69-’71).
The A-arms didn’t have splines to accept torsion bars and lacked the bottom reinforcement on the arm. The cross member didn’t have the support for the torsion bar adjusting arm.
The net result is the conversion to normal suspension required struts, A-arms, cross member, torsion bars, torsion bar lever arms (with hardware) and a bit more. The good news was that your 911E should have the aluminum caliper 911S brakes. Changing the struts, A-arms, cross member, torsion bars and associated hardware would make the front suspension identical to the 911S.
Here is a link to a thread that tells you all you need to know to do the conversion:
