Old car rego NSW.

[Yellow_Festiva]

I'm considering buying a 53 model car. Restored and runs. Has chasis and engine num and was regoed in WA at some point. Is pretty original other than some extra exterior lighting for safety.
Would like to get it registered fully so im assuming just need the sales receipt, blue slip and a visit to the RTA?
Anything else to know in this situation? I'm out of town and am limited in what I can research on my phone.
Cheers, Jason.
