Hi Gary,
Not sure exactly what your bike is like but in general with Sunbeams, there's a long stud that goes through the engine plates. On the right hand side there's a spacer welded to the plate with a sort of crown on the top with serrations that match those on the footrest, so the right side footrest comes off when you undo the nut on the end.
But if the footrests are badly bent, the stud may be too and you may have to  pull that out to get the footrest off, if so watch out for a supporting spacer between the left engine plate and the primary case and maybe another between the two engine plates.
On the left side, the long stud passes through the middle of the primary chain case - but not the footrest. Here there's a thick washer that locates in a slot in outer primary case (so it cant rotate) and has the serrations on its outside that engage with that side footrest.
So in theory all you need to do is remove the nuts on either end of the stud and the footrests will come off left and right, then when you refit them you just have to set them on the serrations so they're a comfortable height for you and level side to side.
I have straightened stuff like this on the bike with oxy acetylene, it makes it easier to get the angle right first time but obviously it's preferable to take them off first, let them cool slowly.
Cheers Rick

Nice image of the bars Sunbeam have used.

Well I voted REMAIN - not so much for economic reasons but more for a lasting peace in Europe.  That went well!
Better stop now Hennie, or we'll get thrown out by the forum moderators for going off topic
