I've got sets from Rover's that are 7.5 rear and various size fronts. I recently sold a Scott Bonnar branded mower that had an identical base to a Rover Combat with a Quantum 5.0 that I got from the tip shop. I used the catcher off it on the Scott Bonnar, identical and a perfect fit. So, if you want some Rover wheels, $20 posted for a set. If that sounds okay let me know and I will do some photos so you can pick which ones suit best.
