Photo showing 8P and 085 box markings. So am I correct in thinking this is a basic Polo box and NOT a G40?

fair enough, I'd have to agree with them then.  If you need to start buying new gears then it's VERY expensive.  Looks like your final drive set is knackered too.  

Having seen that I'd say finding a 2nd hand complete box is the best answer too.

What code is on the casing?

ah just seen your new pics.  Yes 8P is just a normal 1.3 litre 5-speed polo gearbox.  Not worth much at all.  You can find these for sale for not a lot.  They are the usual box to put on a g40 if the original ATV coded box is shat itself and you can't find a proper replacement.  The ratios are similar but not quite the same, about as close as you'll get.  Top end is a bit compromised and I'm not sure it'll do 60 in 2nd with an 8P (which it will do with an ATV). 

Also, you can't fit an LSD to an 8P as they don't have bolt-on crownwheels on the diff.

But you've been using an 8P anyway so using another one shouldn't be a problem, it'll just be the same.

hayesey... what can you tell me about an AHD box? I have been told this is a direct replacement for the original having given the reg no. to a reconditioning company. Thanks.

I think that's a GT gearbox, not the same at all. Much shorter ratios.  An 8P would be better.  I see someone has replied to your wanted thread with a proper G40 box for £200, I'd buy that if I were you.

So the G40 box and the 8P have the same fitting dimensions and should go straight on?

they are the same externally, just different gear ratios.

Ouch, looks like the end bearing on that relay shaft has fell to bits (nothing left there now) causing damage to the final drive set and gear set next to it!

Deffo not worth repairing.

 :(That about sums it up! Things were looking up earlier when I had a good response to my wanted add but the guy disappointingly put his price up when I expressed an interest. Maybe it would be worth it but to quote one price and then stick another fifty quid on top is not very friendly! Disappointing!

Just buy a second hand 8P or CEG gearbox. It really isn't worth paying the premium for a G40 box unless your planning on fitting an LSD?
