Leo, I've had two of the 70 318 SE's. VIN should be JH29G0xxxxxxxx. Basically just a luxury version of the Challenger with overhead console, leather seats, and lots of pretty trim. If you do an engine swap, make sure you've got a decent rearend - I had a peanut in one of mine and swapped a beefy 360 into it & GRENADED the rear the first tie I pounced on it. Also, expect to chnge/modify your driveshaft.
