Task Force window seals?

[sqrlnts]

First off I did try searching but time is money. Only one search allowed every 60 seconds is beyond my patience level.

I have very drafty door windows, to the point that my AC never really gets a chance to recirculate the air to continuously cool it down.

When driving down the road I can feel large amounts of air coming in around the DS window, I am sure the PS is the same. Let me just say I don't have to crack a window to smoke a cigarette in the truck if its moving. I have already replaced the DS vent window seal but have done nothing with the side windows.

My question is will LMC item 38-6118 seal kit stop the window leaks by itself or would I also need the lower seal?

Thanks for your input.
