There are a number of very good and highly experienced jeep denters in Rawalpindi, City Saddar road... as soon as you cross the Nala Lai bridge on Citi Saddar Rd going towards Raja Bazar there is a small lane on the right which will take you to the "Jeep-a-Galli"...the mother-yard for 90% jeeps roaming around in the entire North of Pakistan.
I believe it was sometime around 1989, when we started working with the Awan Brothers .... Jamil Ustad (denter) and his brothers Tufail Ustad and Farooq Awan (mechanics). In addition, there is Nikku Ustad (very good and experienced denter) and also another covered workshop on the left near the end of the Jeep Galli (don't know the owner) where I have seen some of the best looking Toyota Jeeps being made over the years. I have found both Jamil and Nikku to be true gentlemen and will always charge market rates for any job.
By the way, "Toyota Jeep" is local lingo for the 40 series Land Cruiser... which, goes without saying, is the rockstar 4x4 for the majority of enthusiasts in Pakistan.
