Front sway bar frame brackets

[sstaten69]

Hello, Its back to school know so he is still driving the truck tell winter then we will be doing some work on it. Just have to find a place to store the Chevelle so his truck can sit in the garage. Our question is he got a sway bar from pic n pull from a 73 dually, but we didn't have away to get the frame brackets off. (So after finding out how hard it is to find a set of factory ones for sale) we are looking at a set that are for a lowered truck but his isn't lowered yet, but will be someday. Can we use these on the truck even if it is stock or should we wait until it is lowered?
