motor mounts

I am putting a small block 350 into an 87 regal, the car originally came with a 3.8L six. Will I need to change the mounting points that bolt to the frame or will the 350 motor mounts slide right on?If I do need to change them can anyone suggest where I might find a pair new? The junkyards around here don't have any regals that came with factory V8's. Thanks for any help.

But Monte Carlos, Malibus, LeMans, Grand Prix and Cutlass' did. Pick up a set of Chevy motor mounts. Better yet, get a set of Buick 455 mounts and...
