If you are not a slave to original pieces, early unit single side stands make a suitable replacement. The early unit single side stand needs some minor modifications to go over center when extended. But otherwise they work
My '63 Competition "All Sport" also has a side stand. IMHO, I believe all the Gold Star frames probably left the factory with the sidestand mounting lug but not all got a sidestand mounted.
My 62 All Sport frame has no evidence of ever having the side stand attachment. However a 58 frame that left the factory as B34 Scram had a ripped out section of the lower frame rail where a side stand mount would have been.
