Bumpers are around 6.5k new taiwan made and will be around 3.5 to 4k in junkyard,in both conditions you will have to go for paint job cost you around 2k.
origional head lights are probably unavailable but if some stealership posses,it would be around 12k a pair and if you want new taiwan made lights then these are @2.8k each light but i would suggest you to go to Chah Sultan Rawal road for used head lights (origional of Koito brand),i exchanged both light is 1.5k from same market.
You would also be able to find origional front grill in less than a thousand.
For rear shocks and door safe guards, Kiani Autos gawal mandi 0515530621.
For wipers i would suggest you to swallow a bitter tab from stealerships could may cost you around 2k but worth spending.
door rubbers are called channel rubbers which are of 4.5k per piece for one door only at suzuki 3s but you can find them local made from gawalmandi else buy them from Chah Sultan.
Air filter box,again Chah Sultan.
For engine bay,use Kangroo's engine cleaner,i bought it from Metro i/11 in 280 or some thing like this.
