in doing Lt install, i bought the 02 extension for the front and th sims for the back. the extension is pretty long that it sags , what should i do ??? and what about the rear o2 sims..where do i set them once hooked up??

I just tried to zip tie the slack, but they still hang down a bit. I don't see it being much of a problem as long as they don't hang lower than the headers.

FWIW you'll likely get some insufficient switching codes from using the stock o2s the exhaust gas is cooler than stock now the sensors are positioned further downstream, and the stock sensors don't like that, so they throw the insufficient switching code.
Bosch 13111 is the rear o2 from a vette, has a higher wattage heater and is more tolerant of the cooler exhaust gas than the stock ones are, not to mention the wires are long enough to eliminate the need for extensions/splicing wires

This is hot rodding man! You've gotta make some **** WORK.

I've got a 12" and a 24" O2 extension. I've got one zip tied to the master cylinder line for my clutch, and the other side with loop tied in it and it ziptied to the starter wires.
