I have an 85 extracab I recently acquired and am overloading myself with information on this wonderful vehicle. I currently have the A340H with the 22re in front. What are my swap options on the drivetrain combos I can use? I am favoring a W56B from Marlin Rebuilt and would love the dual case setup, but I dont have 1 much less 2 800$ cores for the Tcases they use. I am prepared to spend some money but will not justify 1600$ extra due to lack of cores... Even if I could find 2 of what they want I doubt I would get the full core back based on others experiences. What are my options here cause I really want to get moving on this thing, but can't get through to Cust. service at Marlin to ask much questions. Anyone have any suggestions? Thank you!
