2003 Ram 1500 4.7 liter 02 sensors

Whats up guys, my question is about the 02 Sensors on my 03 Ram 1500 4.7 liter non Calif emissions. It only has 2 02 sensors on right side. One upstream and one downstream. Bought new 02's from rockauto using their patrs lookup but the denso 4719 for downstream has the slots on it's connector offset so it would not fit the connector on my ram, sent it back. The densco 4718 for the upstream is right one. So my question is what should I use for the downstram?

No one knows?

looks to be different for an automatic transmission verses a standard. My standard has four, two each side, upper and lower and all four are the same.

Got this from Rock auto for your truck looks like it covers you all the way around.

Sorry for the delay, been out of the country for a period. Bought 2 of the Walker O2 Sensors for my 03 Ram 1500 4.7 L and should be here soon, I hope but I have another question. Does it matter that the sensors are 2 different brands? I have a DENSO 234-4718 I had ordered before and thought I might go ahead and install it in the upstream seeing as this one is the hardest to remove and install. I have the Walkers coming but though I could get ahead, never know when I gotta bug out for awhile.
