Call Mr. Shahid 0333-5176311, He had a green CJ-5 on stock engine somewhere in G-9 Islamabad, I checked out that ride and it was in very good condition.
I spotted a beige Split Screen Jeep (mid 60s CJ-7) on F-6 double road (if you are coming from Jinnah Super Side), last week and it was also looking nice in stock condition.
Also try visiting Golra Military Auction yard, there are around 8-10 willys parked in the auction yard, they might give them away in the upcoming auction.
