I am pretty sure that the RL60 ones are the same, but perhaps someone else can confirm.
RL60 floor stand part number was 8960187 – these are also used for RL45.
These bargains on eBay don’t specify which model, but perhaps you could ask the seller to measure or look for a part number label (there may go quickly once I have highlighted on here!) Some black hammerite would bring them up a treat: https://www.ebay.co.uk/itm/166420352802
Or if you are happy to spend a little more: https://www.quality-dream-audio.co.uk/stands-furniture-wall-mounts-and-clocks/23030303.html
I have no connection to either of the above sellers – I just spend too much time surfing for bargains!
