Roll Bar, Front Brush Guard & Rear Bumper

I am looking for the following accessories for a 1984 Brat:

1. Roll Bar
   
2. Front Brush Guard (preferably the 'A' Type)
   
3. Rear Bumper (to replace the existing bent-up stock bumper - preferably the style would match the 'A' Type front Brush Guard)
   
4. Stock rear Bumper (in good shape as mine is kinked)
   

Anyone have fabrication drawings for any of these?

Thanks
