Body mount chop and fender trim for fitting 285s and larger tires on stock GX470

[grogugx]

I’m looking for resources on what I need to do exactly to be able to fit 285s aka 33 in tires on a stock suspension GX470.

I have a Dobinson IMS lift kit on the way, but it won’t be delivered until February (due to back order). I have new wheels now so I want to get A/T tires. Anyone have any good resources such as a video or instructions of what needs to be done, where and how much trim?

Thanks
