engine mounts for 318

Yes I still have the 340 mounts , but I also have a few 340 engines so I want to keep them just in case I decide to use one of them in this or a similar car. I was just using a low milage 318 to power my car for while, since I sort of remember how nice it was to get 20 mpg with the original 273 (with gas costing $2.50 to $3.00 a gallon it seems like the right time).
