I have a TRD header for sale it is in good condition but has a bit of a mish mash of O2 sensor provisions, the TRD header itself is for 85/86 so it has the bung for the O2 sensor in the upper half of the header but the B pipe is for 88/89 SC and has the O2 sensor bung in it but there are two, for some reason one of the PO's added a 2nd maybe for a wide band?
