Brother Hankook 40 AMP maintenance free battery is more than enough for your Khyber no need of wasting money it will cost you 5,500 minus 800 for your old battery.
AGS 45AH will also get the job done.
I have ACDelco 45AH on my 1988 Accord 1.6L and it starts in half self.
I even once started a Shahzore with ACDelco.
