Got an xg xr6 the bonnet has bad paint fade so I've got ed bonnet the same color(Polynesian Green) will it just Bolt up or not fit????

No they are different,you need either zg or xf.

Spewing mate cheers for the help do you happen to know what E series parts are interchangeable with xg??

So let me see if I have this right. You own an XG and you have an ED bonnet but you have to ask on a forum whether they are the same. Have you looked at them? Do you have a tape measure?

Mate I think you need to go to spec savers if you can't tell they are different

Basically you have a slightly modified XF body with an E-series driveline that more or less matches the year of manufacture.

And that's not from someone not just guessing. I've owned an XG (white) and a Polynesian green ED sedan at the same time. Fond memories.
