OK, after another near hernia putting the 70 Bonneville on the center stand have decided discretion is the better part of valor.

Recap:
Went to put bike on center stand, cross tube weld partially broke on drive side.
Drive side leg now slightly twisted.

Found a T150 stand which was supposed to be a cross-fit, but while the bolt-hole center to bottom of foot seems the same as original (10"), there is definitely a differing geometry issue.

The original has these numbers on the castings:

On interior of timing side stand leg F5692
On interior of drive side stand leg F5691

Do those narrow it down to a year or model range?
Cheers.

I see no reason why this could not be fixed. After straightening and before welding, I would run a threaded rod with nuts through the top mounts to ensure correct alignment and spacing.

Sorry, I did not read page 2 before posting; I see you've already moved on to replacement.

Re Springs, the stock spring is more than man enough for the job, if it was any harder to put on it would be nearly impossible. i use the loads of washer or pennies trick, put one end in a vise, bend the spring to open the coils stuff washers in the gaps.
Dont throw the olsd stand away , its fixable. Heat to dull red to take out twist, pay the welder.

The stand looks to be casted in the same malleable iron that the foot pegs are cast from? Thus easily bent back and repaired?

Yes
and
Yes but with heat ie as per Gavin's dull red, do not try to bend cold.

OK, you all convinced me the piece should be saved.
Got a couple feet of 7/16"-20 rod to jig the legs.
Anyone have that dimension of flat-to-flat on the bolt holes handy?
