MR2 Parts

Hey all, new here so excited to pick some of your brains.
I’m located in Melbourne Australia.
Does anyone know where I can find original parts? I know of Josh in Bendigo but for some reason his not replying to me.. Hope that lad is well!
Also someone that is reliable to do a roady that has knowledge on MRs?
I have a SW20 with the 3sgte, I did the engine swap and is running like a dream.
1 issue, the oil level light has been up from day one..
Yes the is good! Lol
Any ideas??
