Bottom end and connecting rod bearing size

[Bflorian]

Helo, I want to buy new bearings for the crankshaft and connecting rods, but I don't know what size they are. It's a Renault 4 GTL 1.1 from 1990, and I also idk how to measure what size i need and stuff in case it's not a universal thing.
I'd appreciate any help.
