[Martin C]

Any local welder (= independent car bodyshop or workshop) will be able to quickly and cheaply weld on a new foot, in which case it could perhaps usefully be made a bit larger. If necessary, you could then add a fairly thick rubber base to it by means of a couple of self-tappers (bodger - moi?).

I had to add a rubber base to mine many years ago, after I fitted a centre-stand which necessarily uses the same mounting bolts and thus altered the side-stand's geometry, leaning the bike over to a scary degree.
