Postage size not available (UK)

[stuyvpc]

I am trying to list a motorcycle seat that is 90cm long and 3kg in weight. When I got to the postage options the largest option it gives me is Medium Parcel 61cm*46cm*46cm. I have tried adding the seat length into the Item Specifics but it makes no difference. Does anyone have any idea how I can get a larger size option or even revert to using my own postage options. I am a private seller. Thanks.

You are suppposed to be able to opt out of Simple Delivery for large items so you can choose your own postage.    It isn't working at the moment but see the workaround solution on here:
