SD Model 3D printed engine detail set

I am considering adding more detail to the engine bay. Acquired number of 3D printed engine detail sets made by SD Model. They seem to provide nice level of detail. Resin is brittle, though. Also fit is not perfect for 962C floor. Not 100% certain yet. Main issue will be cross bars connecting rear firewall to gearbox mounts. Might need to re-make them. And oil tank which is molded together with them in Tamiya 956 kit will have to be reconnected somehow to new cross bars. May be too much for my skill level.
