VIC ROADS & Dash Cluster changes

[Scheme]

I have an Unregistered VN Exec, with the shitty standard dash cluster. Being an Exec, it has the shitty stage 1 cluster with Petrol, Speed and Temp.
I've picked up another cluster out of a newer VN V6 that has the option of the Revs tacho. My cluster reads 346,XXX and the new one with revs reads 306,XXX. Being an un-registered car, will I face any problems or hassles when I finally take it to get all registered and on the road, with the changed K's on the cluster?
Is there much stuffing around or is it pretty straight forward? I would think there to be more stuffing around for a car ALREADY on the road changing their cluster.

A little help?

I wouldn't worry about it - any car with over 300,000km on it is worth bugger all. Rego'ing it should be fine.

Cheers mate, appreciate it.

Yeah, they're not going to worry about it.

I registered my 1972 HQ Kingswood with 2,699 miles on the clock. They didn't even blink. They just assume it's been around the clock and back again
