I have rubbing from my 33s I have 3in spacers and need to know if a 98 zr2 fenders will bolt perfectly on my 98 LS and will the tires still rub? If no great if yes best angle of attack on chopping my existing fenders to eliminate the rubbing. Thanks

Sure they'll bolt on, but it's not going to change the rubbing issue... It's the same fender, just with a plastic flare screwed on.

A body or suspension lift would take care of the rubbing.

The biggest tire size you can run on a stock 2nd gen blazer is 30x9.50.

Also, the ZR2 fender flares will bolt on fine as long as it's a 2 door.
With the 4 door model, the front ZR2 fender flares will work, but the rears will need to be altered, as the back doors will be in the way.

They will still rub, you will have to cut a LOT of fender off from the rear of the fender well.
