273 motor mount?

wasn't that long ago I looked high and low for the thicker mount for the 273 that went in the 65 cuda. now I need another pair, can't find the thicker ones anywhere or remember where I finally found the other set???
looks like to me the thinner ones I can find, it pan will hit the k member. why is this SO hard???? yes it has the drop center link... maybe I found them in feebay, I admit to not having any confidence on buying from people on there is don't know!!!!!!!
