The only permit you can get to move it are for licensing purposes. Ie to get it inspected or to go to the mechanic's for repairs in order to eventually become licenced.

If it's unroadworthy, you can't drive it on the street legally. There's no permit to drive a race car to the track. You either have to modify it legally or de-rego it and trailer it everywhere. If you are going to keep it legal, you should apply for a modification permit before modifying it.
I'm not sure how club rego works and/or if its still available but may be something worth looking in to?
