80s?
And I dont think the PML needed any jor tors, especially in 1996 when they got more than 2/3s of majority. PPP on the other hand needed a big jor tor in 1988, 1993 though
NS always needed joor toor (except for 96 as you said) first against his own PM (Junaijo) and then always to keep BB away from punjab. PPP tried their best but they were no match for NS
