anybody ever have a dianna 5g tm apart ? need help

[robert w]

my 5g broke the spring that goes around the cocking link pin hinge and i cant tell if anything else broke . when shooting it the saftey wouldnt unlock ,i removed the pellet and then the subframe discovered how to pop it so put in a pellet and snaped it off outside , then looked inside .the spring seems to hold the front of the bar that actualy locks the piston. i looked at a parts digram and still in the dark. my owners manual shows the same parts breakdown so here i am . need some help as its my go to pistol
