Saw this over on Ebay today. $1170 bucks isn't bad at all compared to doing an 8.8. If you are lucky you could put your 8.8 together for about a grand and that's if you do the welding on it yourself. This one will bolt right in an go.
(However I want to make it clear that I have no interest in this auction, this product, or the company selling it. I just saw it and thought it was a good deal.)
Normally when you see these they are the housing only.
(Hint, Hint, Frank. Christmas for Kat is coming up soon
