Hi there, Jeff here from up in Phoenix...Since your close enough, have you been to 20th St. Auto
Call Larry he can get you what you need
www.20car.com
He also has these (I hope pictures come thru). Beautiful cup style wheels in 7x16 front and 9x16 rears---would be awesome on a 928 genuine Porsche wheels front are part #99336211400 and rear 99336211801, offset front is 55 and rear is 70 - may or may not need a spacer. I have been buying parts from him for 15 years...he wants I think $1200 for set, but considering one rim is $1400 from Porsche.
