AussieHolden - Apologies, I meant that nothing like the way you took it. If we had been sitting at a table in the pub discussing this over a beer, you would've seen the grin on my face and realised it was very much tongue-in-cheek.
My point is that many eBay sellers will tell you anything - whether they know the answer or not. How many times have we all seen a VY cluster on there, advertised as being able to fit VY series 1, series 2, or VZ?? The fact is the NO VY cluster will fit in a VZ, and if you fit a series 1 VY cluster into a series 2, the fuel gauge works in reverse. It can be fixed, but it takes some programming trickery or a $400 replacement sender assembly! Funny thing though, they never write these details in the listing - simply because they DON'T KNOW!!
I believe NOTHING that these bozos tell me - I research it myself before I buy
anything on eBay. You have no comebacks, apart from the feedback system they have - and who really takes a lot of notice of that, as long as the seller's rating is in the high 90s??
I would be VERY surprised if this bloke's "kit" contained everything that is required. Refer to my list above - it's quite a comprehensive one. From Holden, you would be looking at a couple of thousand bucks easily - more probably - and it truly would be a major undertaking to strip the car sufficiently to remove the old stuff and fit the new. It's a job I'd actually be hesitant to take on, and believe me I've had a lot of VY and VZ dashboards in pieces - both standard HVAC and climate control models.
Anyhow, sorry again to have offended.
