None exist that I know of. However you find a shop to fab up the pedastals, the rest is normal swap stuff you find on the many ls forums. I have only stuck ls motors in older Gm body's but my bud has 2 '66 Stangs, I want to toss an ls motor in.

If I was still in the Bay area, I would have Mean street fab something up Picked up a 1970 Fastback Boss Clone. I already ordered the CCW's, Baer Brakes, Total Control front coil over and rear 4 link coil over..has a 302 in it.. But I want to go fast and swap parts for LSx are easy to get.. just not for a mustang
