Old style gussets
It sounds like you have the pre-1993 gussets. I had to order the new ones (W-425s) from Van's for my ancient wing kit too. I can't tell you if it would be worth the trouble to replace them. Lots of early RV's are flying with that older design. They are known as W-419s on my old RV-4 plans and were hand made from .040 sheet aluminum.
