Hahahahahahahahaha
Yea ask me how difficult it really is 
I have been finding it for long long time...n it's too too too too too tough to find...especially 929s as I haven't seen any on the roads now...also pakwheels & Olx sees only one or two in every six months to a year...and trust me those are ultimate spoiled ones...some having Indus Toyota lights & bumpers...some having spoiled body...some totally scrappy interior.
So in fact, the kind of excitement makes me on the cloud number 9... 
@skysedan I haven't seen a few of them which could be spotted in Lahore previously on the roads from quite a while now. I know two in red color, one of which used to be parked in FC college Lahore...other in canal view h/s Lahore with a Lahore number "150"
Islamabad has a lot of 808s. I saw them running on the roads. Also Mazda 1300 can be seen.
Don't know the situation in Karachi as I saw a lot of Datsun, old charade & old starlet but could not spot any 929 there aswell.
I think if they are running in Karachi then it would be easy to get the parts from there. Whatsay @skysedan?
But regarding the condition, you are right, most of the cars are being dragged around in pretty bad shapes as taxis or as off-roaders in villages.
Most of the parts are either forcefully fitted of newer model cars.
