I believe you'll want to ask the moderators to move this to the VINTAGE KIN sub-forum, first, as it will gather more attention there.
Second, I'd join and post this question to the SILVER STREAK MAILING LIST
Tom's E-Mail List Page
Third, have a look at this great blog on a shell-off
Silver Streak restoration currently underway.
1970 Silver Steak Sabre - Model 20
At this time I'm not aware of other resources online, but someone here or at one of the above may be of help.
Please post what you find or don't find!
