While I have the rear dropped, what can I do to remove the rust. Car is a play toy and not a show car, and I'm not looking for perfection. pics:

Wire wheel and white vinegar, or muriatic acid.

I've got a bottle of muratic acid that use for the swimming pool. Does it remove rust? Maybe brush it on with an old paint brush, then wire wheel everything off?

It will remove rust rinse with water and keep it away from the aluminum calipers.

Perfect. I'll give it a try and post my results. Thanks for the advice

No problem be safe with that acid.

wire cup wheels are great to remove rust. just please wear safety glasses, the little wires will break off

Follow the directions to a T and it will turn out great I have done it to a bunch of rear housings and it hold up awesome
