As the title says I have a 1980 K10. I am going to be swapping in a 03 lq4 with 4l80e trans. I need to figure out what will be the best T- case to use. It will need to be drivers side drop and I would like to have the Speed sensor so I can still have cruise if i decide to do that. It is DBW. I am also wondering what type of adapter I will need. It is a 12 bolt rear.. and i think a dana front 10 bolt?.. not 100 percent... Im not at the same location as the truck right now... Also need to be sure the case will hold up to about 500 to 600 rwhp... my future plans involve a big single turbo..

Thanks
