Is there a preferred type of all bottom end bearings and piston rings that are better than others?

Black sun visors with lighted vanity mirrors, really nice shape, Auto Seat belt controller (part number MB435513) sell all 3 pieces for 35.00 plus shipping. For pics just message me with an email or cell and I will send pics.

is there an actual part number or should i just bring old bearings to a bearing shop and match them?   from coldscrips restoration...he says he got them from ulrichwolf....sent him a message a month ago but no reply...   http://i719.photobucket.com/albums/ww192/ColdScrip/P5120260.jpg

Any ideas where I can get decals for my 86 conquest???
