If you are going to Saddar from Faizabad, then don't go in Committee Underpass, just cross the overhead signal of Underpass and Muhammad is on right side of road ..
Yes, you can find genuine fuel tank and side covers from Muhammadi, It will be having recent sticker
now you need 1998 sticker, which @Automotorsport_Lover can tell you, where to find ..
