Ring gear / flex plate

[Rexus]

Hi there

I have a 2008 XC70 D5 2.4 Diesel engine (D5244T4) and I cannot for the love of my car find out if one can order the ring gear separately or if it comes attached to the flex plate. Additionally I cannot find the correct part number.

I have found them on Ebay, but there are not enough specs to verify if the item I am looking at is correct. Additionally the prices vary so much it puts the proverbial spanner in the works.

If anyone can tell me what the correct part number is, best place to buy it and what sort of price I should be looking at.

Any help would be greatly appreciated.
Regards
Tyron
