Sir, best option is to go in an Auto Supply dealing with Toyota's, brand new is still the best, though it would be expensive, peace of mind of having a new one is priceless! Though a you may also try at Banawe or even in a surplus shop.
nagtanong na ako dito sa toyota baguio.d daw maaccomdate ang mga lumang car at wala din surplus kung meron man daw baka may tama na rin....any suggestion kapag external ung km\h ha tnx
