That 1st sentence is true, the rest is questionable.

How fast did your brakes wear out? What problems did you have?

I've got 50 k on my rears and no signs of trouble yet. The original brakes went 120k. I'm on my second set of front pads, the first went close to 40k.

What upper arm issues?

89 had less than desirable gearing if equipped with the automatic.

Most if not all electric problems I've had on Dodge trucks have been caused by previous owners.
