4,500 dollars for a 8 & 3/4 .....?

Sorry, the next $4500 won’t be for a singular part like that. I don’t care who’s magic wrench was in it.

That's the bottom line. It's not going to make your car $4500 , $3500, or even $1000 faster.

And for cool factor: you can't even see it behind the car looking underneath like a Dana.

...and you can buy an aluminum centered Dana way cheaper than this. Probably close to doing a 8 3/4 adding the cost of the MP aluminum case.
