Which Daihatsu parts are compatible?

You would probably still have a problem because the placement of the leafblade mounts is too wide for a ke20. The old celica/carina axle is pretty good I think, since ae86 pumpkins will fit in it.. There are places that sell leaf-spring mounts tat you can weld onto the axle yourself, otherwise it might be possible to take them from an other car all together (there are plenty with leafsprings out there, and the system is pretty much the same on all of them).

Ring and pinions would only be interesting in 4.3 and shorter ratio's.
4.1's can be found quite cheap from Richmond gears, who make them for a small racing class in the US (Legend cars, they use an old toyota axle).
210 dollars or something....But I dont need a 4.1 , I already have a good 4.1 in my basement.
