Im installing a set of longtubes this weekend and I need some o2 sims to get me by until i can have the rear o2's turned off. Does anyone know where i can get these? Is there a difference between the f-body sims and the vette sims?

 

I got mine on the for sale section on here for F/ bodies for my 99 Z28 last year.

I would think they are the same as all the simulators do it tell the PCM that your cats are working and the air/fuel ratio is correct.

They just plug in in place of your rear O2's sensor so plugs will be the same.
Mine worked fine for months until I sold my Z28.

I just looked at Thunder racing web site and part numbers are the same for Ls1 F/bodies and C5's

You can get them here:

ive got some (i think) that are brand new...i never used them

 

If your going to have them tuned out why bother with the sims? They won't affect the car except having the check engine light on. Waste of money in my opinion, put it toward a good tune.
