It looks pretty close to about right to me.
If some comedian has removed the bosses on the rear forks on which the stand normally rotates I can see your difficulty in fitting the stand. I have multiple mods on my 1937 RH500 to make the rear stand work. As someone said when following me yesterday on the Side Valve Rally run "Your rear stand isn't straight." Indeed, it rarely is, although that does occasionally happen. My frame has seen a lot of abuse over the years, is far from straight and the stand bosses are worn away in places. But the bike handles notoriously well, the stand holds the bike upright and so I have no complaints.
Feel free to PM me as necessary to see if I can help resolve your problems.
