I used the trans dapt mounts only problem I had was the bottom holes were to far from the top, I just drill the bottom holes bigger now they fit fine. I have the trans that came with the 4.8 and the mounts set it back about an inch and the stock Burbon driveshaft fits great. Oh and paint was crap a little rattle can can fix that. As for the fuel lines I'm using this guys idea www.ls1truck.com/forums/238259-post16.html, uses dorman 800-078 + 800-058 = 3/8 line and 800-079 + 800-057 = 5/16 line got it from amazon with free shipping for about 40 bucks.
