So sorry rvtjonny. That really sucks BIG! I know the feeling all too well.
The thing is, these SP's are getting more and more rare and they really are quite unique. I would take the time and a least comb the Internet for the pars needed and make a calculation as to what needs to be fixed. If it's within reason, time and budget, fix it.
Even if you do it over an extended period of time to prevent a sudden hit to the pocket, do most the work yourself and find the right parts, a time will come when you will ride again, and maybe even enjoy and appreciate it more.
I have had 2 pretty a bad falls. 47 stitches and some serious loss of skin was the worst. I learned dearly from each of them and do find myself being more cautious.
There is a freedom that comes with biking and a joy that comes with a v-twin SP. You may not see it now, but it will be a worth while experience.
Hang in there, I hope you start feeling better soon.
