Just bought a chrysler lebaron

I ran a rare TII auto in mine. Long story how I got it but it had al the good things in it. I swapped the transfer gears to get a 3.22 final drive ratio instead of the stock 3.02:1. Mine had the stronger axles and HD carrier bearing assembly. Like Billcom said, it was truly bulletproof but I never did anything crazy with high boost or exceptionally high load high stall starts. I miss the car but rust took it out.
