FRAME SWAP

I recently bought a 2007 Grizzly 700 EPS 4x4 injection that has a tweaked frame. From the forum research I have learned that there are possibly some Grizzly 500 frames that will also interchange.

Could someone tell me what year, size, model grizzly frames are interchangeable with my 2007 Grizzly 700 EPS 4X4 injection?

Thanks for the help!!
