Urgent Help with type 3 wiring !

hey all , got a 71 type 3 and i wanted to know if any of you fellow dubbers are good with wiring ?

my type 3 thought it would be great to have the voltage regulator die and this cause 2 of the wires coming from it to draw to much voltage and fry the wires.

i got a new voltage regulator but need the wiring replaced , im willing to pay , just not sure what wire / other things i will need to fix my problem

the car is located in calamvale QLD if some one can come have a look and sort it A.S.A.P that would be great !
