340 in a 87 dakota truck

any one know where to get engine mounts, and trans mounts ? 340 -904 trying to put in a 87 dakota pick up? thanks
Dude! I love it! I had an 01 Dak 4.7 when I got my 340! The 4.7 was a ripper, but I had a thing for putting it in there, and doing the 440 HP block in my Sat. ...killer idea! And that's a light truck! On another note, I knew a guy that had a 440 powered lil chebbi luv on tractor tires... Yes 340 Dakota!
