I ordered a part for my Bonneville and they sent me the wrong oxygen sensor. At this point im willing to let it go for free...

Parts received.

2 days,,not too bad.....

For A/C Delco, I go with www.rmsautoparts.com. They cater to the F/Y/B-body crowds, but a lot of the peripherals are common (02 sensors and such), and they can get anything else quickly as well.

There'* always Dal at VanDevere Olds at lockitup@bright.net, or (for a quick response) call (877) 448-5451. Call early, though.

Those two give about the same pricing, which is cost + 10% on most things (GMPD pricing, or a little better), with reasonable shipping.

EDIT: I should have read the post more carefully, as I it'* referenced above.
