Hi Tom - best I can figure out there are some differences you will have
to deal with.

Your truck was a 98 318 - but what year 360 did you put in it? Did you
change the ECM? What year is the ECM? It looks like the 360s in 1998
used a Bosch O2 sensor part# 13280 before and after the cat.

The 318 in 1998 used a Bosch part# 15705 before and after the cat.

Tomarrow I'll take a look at the sensors if I have them in stock - and
see if I can detrmine if there are any obvious differences.

If you have a newer 360 and/or newer 360 ECM - the ECM may be looking
for more than two O2 sensors... sometime after 98 - I think it was 2000,
they went to a four sensor, O2 sensor system.
