Hi Shaun-
Sorry I can't help you with the details since I don't own those items, but I thought I might make a couple suggestions.
First, if you CALL Weber customer support they may be able to give you exact griddle dimensions. If you email they will probably just give you the numbers off of the box but if you call and explain what you want they may be able to help.
Second, if you include photos or links to the griddles you mention you will probably get better response since more folks are likely to recognize the picture than the part numbers.
My $0.02.... Hope it helps.
