Dosent bobby long offer some good ujoints? I think they are machined for full circle clips, and mabye some other mods. I don't know if they offer them for toyotas or notm but here is a link. http://www.toyotasuperaxles.com/
They are a little pricey at 150 ea though.
They might be worth it if they don't break. There is nothing worse than a broken U-Joint.
