Sorry bro for late reply as I was hell busy but ofcourse i cannot forget you; my pakwheels family so summarizing all answers one by one:
@luckycar
1. Dear for rust issue, immediately take your car to Good suzuki dealer preferably Mandviwalla or Macca Motors. Get your car fully serviced by removing carpet, seats etc. & they will first wash your car from down & inside.
Then tell them to undercoat with antirust spray/compound. Prefer 3M products. They will stop rust better, then repair your already rusted parts.
@KamranAslam can better inform about Mandviwalla work quality
Your Kenchi seems fine(or atleast seems fine in pic) but anyway u replaced it.BOL:)
90/100 Watt bul brand u mentioned is crap. Cultus wiring & fuses are not capable of supporting 90 watt(Even if relay is installed) or other option, install heavy wiring for 90 Watt bulbs
Cultus original wiring can maximum support 60-65 Watt 
USE ONLY PHILIPS 60/65 WATT.Their light will more luminous than 90/100 watt koito/koyo/bosch/Lambda atc.
Steering should be loosen by now
