Hi Gil,
I am in the UK so used UK supplier Simply Bearings
https://simplybearings.co.uk/shop/Bearings-Oil-Filled-Bronze-Bushes-Oil-Filled-Bronze-Plain-Bushes/c3_4511_4770/index.htmlI used these AM0812-8 Oil Filled Bronze Plain Bush 8x12x8mm or SKF PSM081208A51 Plain Sintered Bronze Bush Bearing 8x12x8mm for direct replacement or these AI0508-06 Oil Filled Bronze Plain Bush 5/16x1/2x3/8 inch if you want to ream the bush and bearing housing to a really snug fit.
The bearing housings will accept 12x10 but i could only get 12x8 but the needles are about 8mm wide inside the cage so pretty much the same.
Kind regards
Ade
