I agree that the '86-up Toy drums work great... IF kept clean. The only time I've ever had problems with them was when they were gummed up with mud. Other than that they've been flawless. They are also PLENTY strong- its the stock proportioning valve that makes them weak, and the problem seems even worse when you add larger tires. An aftermarket manually adjustable valve can easily get the rear drums to lock up too early, so the brakes themselves are not the problem.

The FROR kit is the best there is for a Toyota, but I agree that its expensive and far more than what you need. Even most heavy duty wheelers will never break a stock rear axle shaft.

The Sky kit is affordably priced and seems to work well. However, I've yet to read of anyone who was happy with how the e-brake function of GM calipers performs. They are also sensitive to adjustment, not to mention expensive. A lot of people who went this route did it mainly so that they could do a rear disk swap and still be able to pass an inspection.

The t-case brakes work very well when adjusted properly (far better than stock), unfortunately its not an option for you.

The bottom line is that there is no cheap/easy/complete rear disk kit available. You have to compromise somewhere...
