lets see if u can understand me...
if u from jalan gombak there's a junction to go to sentul. when u turn to that junction just go straight untill u find a corner to sentul. the chop shop is at ur left hand side. if u go from sentul u will find a junction to go to kuantan.DON'T TURN.just go straight and u will find the chop shop at right hand side.if u go from gombak u will find a T junction and turn left and go straight and u will find the chop shop at ur right hand side.
hope u can understand.i've describe it the best i could.
