Yeah, I don't think Toyota put their names on radios until the 80's. I've got a little mp3 transmitter that plugs into the cig lighter, so I'll hide some speakers in the back where the originals are and use the original FM. I haven't checked the tape deck yet, but I've got heaps of old tapes :)
The rego. I really want to use it, but I think vicroads charges 400 bucks to re-issue the plates, even though I have the plates. My hardtop has original B/W plates and was registered 1 month before this one. That will cost 90 bucks to transfer, so economics may dictate me going with that. It's a shame because the plates are in such good nick. Maybe one day!
