OOP, what is the best practice to use two different Retrofit implementations in a big project?

I have a situation where I need Retrofit instance with caching , but most cases I use default Retrofit instance, I know that caching require using OkHttp client, but what I need is an elegant way to use those two instance without replicating code ..

I thought that I may use Dagger to handle this, but it's an old project and I'm trying to enhance it one part at a time. any thoughts?
