Depends what year motor you are looking at. The 488 bolt pattern will fit a 727 Early Diesel T/Flite I have two cases for that combo. Also depends how you plan on starting it. The later DP with the 513 motor has an an adapter for a GM Glide or T350 and both have different starting methods. Calll me @ 985-804-6161. I have a Viper with a t/f here that is for sale, and I had another. And can probably help you. Jeff Teuton or email
