I found this guy on Ebay selling adapters so I asked him some specifics on getting some made. Here's his reply:

A set of 1.3" thick adapters run you 135.00 for a set of four. We also offer lug packages for mounting of the adapters to the hubs for 15.00 total for all four wheels.
We do have the blanks in stock and can ship in 1-3 days from receipt of order. Thank you for your interest in our company. I am sure that you will find that our adapters are made of the highest quality aluminum and with expert craftsmanship. We stand behind our product and hope as a happy customer, you will pass the word about our product.
If you would like to purchase our product, you can go to paypal.com and send funds to adaptamerica@aol.com. ( any extra cost for options should be added to shipping in pay pal) Be sure to leave all info on the application as well as a daytime number for UPS and also include 15.00 for S&H. I also accept money orders that are to be sent to Keith Patterson at 7504 Foxtail Plc, Crestwood, Ky. 40014.

I post this only because I've seen other sites selling adapters for well over $200-250. I plan on getting a set next week to start the 17"x7" upgrade. Any input is welcome, pos or neg.

 

Is there a link or something? 140 is pretty cheap i would like more info regarding his company.

 

The adaptamerica@aol.com is the email address. I have contacted him through this address before. I found him on eBay and I'm not sure what his seller ID is. I do remember that these are billet 6061 aircraft aluminum. I'm buying mine next payday.

 

the 1.3" adapters hes selling are for 33mm offset rims.. with those adapters id go with 33.. offset and a 7 or 7.5" wide rim...

 

Recieved the adapters and they're top notch. Anyone looking should drop this guy an email. I gave $165 for adapters with lugs which includes the shipping. Check the first post for the email address.
