Anyone running 10" wheels up front (w/disc brakes)... How?

[100mph]

Hi, I'm a bit confused... I've put drop spindles/disc brake kit on a truck I bought that came with 10" wheels all around - backspacing seems to be about 3.5" to 4".

I honestly wasn't paying too much attention to the wheels prior to the drop spindles as to how far they stuck out but now they're out almost 3".

I read last night that CPP has newer spindles that should bring it back about 1.5" but that's not quite enough from what I can see.

Soooo... I just wanted to know if anyone else has had the same problems or is running with 10" up front w/disc/drop spindles??

I know 10" isn't too common up front my problem is the truck came with Boyd Cottington's Nemesis wheels -for the price of two 8"'s I can buy a new set of 4 all around (and maybe tires).

Also, as a side note as I'm fairly certain I'm buying new wheels - what are people running with this setup, I'd like to keep 10"'s in the back and 8" up front - would 4.5 backspacing work for both??

Thanks guys!!(and maybe ladies)
