It is definitely the top steady. I went to feel the loose bolt and I could pull it out so it has sheered at the engine block. It is basically flush with the engine block so I'll try a screw extractor and put a new bolt in. The rubber on the arm itself seems to be fine.
If you can't easily get the sheared bolt out the block, Somerford Mini sell various repair kits as listed below:-

Broken Steady Kits
"What's even more frustrating than worn out upper steady bar bushes is one or both of the mounting bolts shearing off in the cylinder block when you try to replace
them! Sometimes one or both block bolts have even been sheared beforehand by the shock caused by ineffective bushes. Either way, a classic situation of a five
minute job turning into a major exercise can result if engineering workshop techniques or tools such as 'easy-outs' are required to remove the remainder of the bolt(s).
Somerford Mini can supply an easy-to-fit mounting bracket assembly which bypasses the use of the offending engine block bolt holes.
The four broken steady kits provide alternatives for use on cylinder blocks where either the longer bolt only or both bolts have broken, on engines without or with
a crankcase breather on the flywheel housing (the latter for 1275cc engines from 1969 on). Each kit includes an adaptor bracket, plus the bar retaining bracket
with appropriate bolts and washers."
