Turnbuckle and Screws

[Divefire]

Well that doesn't sound to dodge a title... Anyway!

I could do with some pointing in the right direction for a good source of screw sets and turnbuckles. It's to fit a XXX BK, which is having some issues with the screw heads stripping on the underside of the chassis, they were Losi replacement items so I don't think I'll be getting the official ones again any time soon...

Turnbuckle wise I could probably do with the full set, though when I was looking around at the end of last year I was hearing various things about suppliers and quality of the components, any one got any good tips?

Thanks in advance.
