Hi. I haven't posted for a while. I finished my truck in June and have driven it about 1500 miles. It has the original 261 installed w/ the sm420. I did change the rear to a 3.38. I'm considering changing the trans to something else with an OD. I have even thought about an auto like the 200-4r. But the question is, I have heard the A833 will be a direct bolt up. Is this true? or am I better off with the t5? Thanks for the help, the advice is always good.
