If you know Sarfraz Bhai than dont waste time, contact him tomorrow morning, get the number of Afzal Sb, go to his workshop, show him your vehicle, he will get you everything that you need. Everything includes everything, so dont worry.
It will be quite hard to find a vigo's rally suspension that is yet to be abused in a rally, if you are serious in rallying, buy new stuff. Put aside 200K for all the required goodies.
Afzal Sb will fabricate the dual shock mounts in front, reinforce the tubes, radius arms ect, fabricate the roll cage and snorkel. He will be able to inform if someone is selling any second hand stuff and last but not the least, will get you a Megafire(chip). You might need to get a shortened back, but if you are new to the rally world, would suggest that you start slow, i.e. do the basics like suspension ect and them develop the vigo by the next rally/Cholistan
