Ian,
Pictures sent …. but one wheel only. It transpires the other is a Slough rim. Sorry.
I did a lot of “front-end” work and found a Slough rim and tyre as good as (if not better than) the various designs of hub-locking tools when undoing the main driveshaft nuts. Having a large clear hole in the centre, those nuts could be accessed with the wheel fitted and chocked and thus using the weight of the car to prevent the hub turning.
