There are mere chances to find LWB in Pakistan. I did try to find but most of them of very old, poorly maintained with engine/gear are changed. Those in good are not for sale or demand won't look reasonable.
Luckily i owned one of them but not in PK. I hope to bring home if policy allowed in near future.
Here are few glimpse of it.
Best of Luck for search.
