Replacement O2 sensor for a Howell TBI conversion

[TheBeardedOne]

Hey guys my 74 has a Howell TBI conversion on it that the PO installed. I’m needing to replace the single wire O2 sensor and was wondering if anyone could recommend a replacement. Thanks in advance

try a 1990 Chevy 1500 with a 350.

early 90s GM EFI, early 90's GM parts. The above is probably correct. Look it up on Rock Auto, pull the picture, make sure the plug looks about the same (color doesn't matter, shape and wire count does). Wire length looks about right? That is the one you want.
