Since you posted in the classifieds I can't directly reply to your question.  That is a large range of Mustangs to draw from.  As you are interested in a L.A. pickup, have you tried Pick Your Part in Sun Valley?  Today (New Years Day) is the last day of their 50% off sale.

 It's $2 to get in, $3 to have each tire pulled (if you don't want to pay for it) or $12 for a set of four removals. There is a $1 core charge per wheel or $4 per set of four. The wheels are $14 (or $7 each @ 50% off). Tax will be about $4 and the hidden "environmental surcharge" I'll estimate at $3.

  So, that is $2 + $12 + $4 + $4 + $3 = $25 in "charges" - plus the actual $28 for the four wheels,  at 50% off.  That will be right about $53 of which nearly 50% of the cost is "charges" and not the price of the wheels alone.  Yes, I have some "not so hidden griping" in this post over their pricing. On the other hand if you want the wheels in the L.A. area..., it may still be your best bet.
