M_Boats: favor to ask

I have a favor to ask of the group, could you tell me the dimensions of the boom that I need to ordering new end fittings? I would like to order new end fittings from Dwyer (one of the groups previous great suggestions!) but I have not been down to my boat in a month and it is two hours away so too long a trip to make just to grab the boom. The Dwyer site lists the fittings by the maximum cross section dimensions of the oval, which is from the slot to the bottom and the side to side width. Thanks! Robbin M-17 hull#056
