I'm not sure why this should matter to you as an end consumer. Most companies use this type of tool to increase thier profits, not pass on discounts to customers(unless necessary to get their business in the first place).
And those prices seem right on par with what we pay here in New Mexico...
I like it. My FJ was my favorite all time vehicle to drive, I may be looking into another one soon. If something like this were to come out I would probably be looking at this instead.

Well almost anyway. I welded up both of the mounts instead of this method but the end result was the same. Total cost was <$100.
I have them on my 4runner now and I disagree completely, they are not "smooshy" at all. I also had them on my FJ Cruiser and they were stiffer than stock. Both are/were the 5100s.
I think for ~1/3 of that quote you can get a rebuilt long block and forego any of the home rebuilt time. I suppose it all depends on how confindent you are R&Ring your motor.
