Ring and Pinion install price?

I didn't think that price was high.You can buy the tools and try to do it yourself,but it is more than just measuring things,most times the pinion depth measurement the give you does not produce the correct pattern.The pattern is what dictates if it is correct not their number.Most people forget that it is not just someones time you are paying for ,it is their knowledge also.If you have never done it you can either pay him now or pay him later and buy a second set of gears when it doesn't work out.
