Help with wheel and tire package

Hello all!! I am in the process of getting ready to order wheels and tires for my 300FW and I am having a seemingly difficult time finding what I want on a few different websites as a complete package.

I am looking for the Kenda Bear Claw tires in 25x10x12 for the rear and 25x9x12 for the front mounted in ITP SS212 wheels with the proper offset of 5+2 in the front and 2+5 in the rear. I have been trying to build this exact kit for days now on RMATV.com and cant get the kit to come together. It’s as if they don’t offer a 25" for the front even though I know they do. Any suggestions or other websites that assemble one big package?
