Okay several questions before I begin this swap.

1. Is it okay to sandblast the old GC steering box as long as the high & low pressure line holes are plugged? Is there anything else I need to be concerned about before sand blasting?

2. How do you really tell if the unit is okay before putting it on?

3. Are there any seals, etc that I should replace before putting the unit on?

Thanks,

Bart
