Hi all , I just purchased a basket case 1990 fj62 non- running , I got lucky when I tracked down that the fusible link wire for ignition was broke , replaced it now runs however the PO rigged the exhaust system and removed both o2 sensors down pipe and was running it with any sensors at all. I ve searched the web for replacement down pipes or headers that have the o2 sensor holes in them but am having trouble finding any . Help please ...thx
