suspension upgrade for 1976 F100
Does anyone have any ideas on how to beef up the rear suspesion of my 1976 F100. Here is the deal it rides nice handles well, but I can't carry any kind of load without the back end going way down to the ground. Ultimately I would like to raise the backend about 2 inches, increase the load carry capacity, and not loose to much of the ride quality I now have. Any ideas would be appreciated. Thanks in advance.
