I'm sure Steve will pop in on this one and give you some suggestions, he kept a stable of TTUL's flying for years. If he misses the thread send him an email at email@example.com
. You really should replace all those parts with APA's or other LE connectors and hopefully the standoff connectors can be replaced with with Jaco's or another style too, Prism used a similar style at one time, Steve knows what works.
Even if you could find a source for the originals they are as old as yours and ready to break, I bought a new, sealed in the original bag, Utopia a few years back and the fittings broke in an hour after assembling it and hanging it on the wall
Fine fittings when new but the material didn't stand up over time, nobody knew that then though. Hope they didn't stain your sail.
