oops, i didn't factor in the 280z stub axles and companion flanges in, or the front mount...i'll make it, so thats pretty cheap... i got my diff & axles for way cheap, probably spent about 200 for them. i spent 60 bucks on my boots, Also i'm using mas280's adapter, and going to get the cheaper A Zcar moustache bar. and if you think about it, the brace isn't really a part of the diff swap, as it holds the control arms...
but, you're right, it is a lot more than 1000.
