restore it to original specs. search & post request over this forum for a fibre top. Change of body shell over a CJ frame is not only a tricky task you need some paper work to keep it legal.
The RED jeep in picture, with due respect i have a hunch it is not even a original Jeep from CJ series. It look like Pakistan assembled SHAHBAZ variant of Jeep from Gandhara Motors in 70s'.
This very vehicle will eat inside out your financials and not be at par to perform as Jeep 4 x 4. At 1st opportunity sell it off at same or bit more of price u have paid for it.
have patience and keep looking for a vehicle which is ' close to original specs with no swaps in terms of engine & body shell plus the papers be in right order '.
restoration is a pain staking job require patience knowledge & enough spare financial resources to get work completed in 3 months later of anticipated date.
thats my 2 cents - seasoned 4x4 addicted users from Unimog, Frontier 4x4, & IJC groups will guide you further.
