Pistons & shell bearings you might find locally.
A good (old fashioned) engine reconditioner will have a network of companies he can contact to source parts. They will probably be well known brands.
When I struggled to get +.020" rings for my 6-cylinder motor one company tracked down rings but even the owner said that they were too expensive, another company found +.060" pistons without trying too hard.
