Window Moulding Weatherstrip Belt for 2008 Tundra

I own a 2008 Tundra. The window weatherstrips are rotting so I ordered a set of 4. Here's the problem. The company sent me 4 of the long ones that fit the front windows but do NOT fit the back windows. The back windows are much smaller then the front. Originally, I told the company it was a CrewMax. But, I own a Crew Cab Pickup. V-8, 5.7L, 4WD. Not extended.
My question: Can I use 2 of the window weatherstrips for the front(Driver & Passenger), and have the company send the correct size for the back 2 windows? option 1.
My other question: Is it possible to measure and cut the ones they sent me(All the same size like the front)by making it smaller to fit? The weatherstrips on the back seem to curve down.
option 2. if possible?
Thanks

I don’t know if it’s possible to cut but for the future you have a double cab not a crew max.

 

I just replaced mine, would recommend ordering the correct ones vs cutting. The ends are different than just a strait cut.

 

Like @ARayT said, don't cut to fit, see if the company will swap, or send the correct size. There is a clip at the end to hold it in place. If you have questions, hit up @Roman he works at Cool Springs Toyota and is pretty active on this site.
