Front or rear sway bar?

[68 P.O.S.]

I bought a front end rebuikd kit and 4/6 drop kit from ECE. Decided to buy sway bars while I was at it. The front bar is from ECE (1 1/4") and the rear sway bar is from CPP (1 1/8"). After installing the drop and front end rebuild kits I had a ton of tire rub on the front inner fenders in all driving conditions. I first installed the front sway bar and drove it for a week. The tire rub was greatly reduced and handling was improved a good bit, nothing spectacular, but a helluva lot better. When I added the rear bar the tire rub was almost eliminated and now the long bed drives almost like it's on rails. For me, both sway bars together were a fantastic upgrade and would do it again in a heartbeat.
