In search of Bi fold Hatch Parts. Buy or have to fabricate?

[american outlaw]

Any leads on 03 Bifold Roller? or a 10L/10R Inner Lock? I figured Id ask yall before I start going wild looking for something that is good enough. Thinking of buying some Delrin plastic and pressing a bearing into it to go onto the post for the roller. Then, it might be a pain, but I could fab the inner lock as needed. Would like a not homemade jank tho
