Simply call/pm Travis (daytonayellaz). He has the cleanest drop outs and is very knowledgeable on LS swaps. He can get you any set up you need. Low mileage as well. I bought my ls2/4l70e swap from him and could not be happier. GREAT PRICE TOO!!!!!!!
No need to look around. You will not get a better beal anywhere else. I looked for over a year to try and find a better deal but could not.
