VTO Wheels has some wheels with 4x4.00 (101.6) bolt pattern in 14 and 15 diameter. They are made in America or at least their sales office is in Arizona.
They offer mini-lite look-a-likes in a 15x6 with a 4x101.6 - check older MG or Jensen Healy link - these are a good replacement for your 13" Cosworth Vega wheels.
BTW, BF Goodrich is now making 205/60-13 Radial TA's, check their website or Tire Rack, Coker Tire. I bought a set about a month ago from Tire Rack. There's another post here on h-body.org.
Anyway, VTO Wheels has a
Retro 4 wheel - which looks a lot like a Vega GT wheel,IMHO or the American Racing Libre - in a 15x7 size for a Mustang and 240Z/ B-210 in a 4x114.3mm(4.50").
So they should be able to do a 4x101.6mm in the Retro 4 - lug area is solid all the way around.
The 4.4" backspace is perfect for a 7" wide wheel since the 13x6 Vega GT wheel has a 4" backspace.
The 2.87" hub bore is larger than the Vega's 2.00", so that may be a problem due to the lack of metal. The hub bore on the 15" Classic 8 and a 13" Retro 4 is 2.64, so a bit more meat for and that may be their concern. Well, maybe not - here is a
14X5.5 Retro 4 in a 4x100mm with a 2.87 hub bore. they can do it.
Also,I assume that these wheels are NOT hub-centric since they are for older cars.
Here is my entire conversation with a guy named Barry as of 5/10/2018:

Customer12/11/2017 8:53:56 PM Do you custom drill 15" diameter Le Mans or Retro 4 Wheels?
I would like a set of 4 wheels - LeMans or Retro 4 - in 15x6 or 15x7 with a 4 x 101.6(4.00 inch) bolt pattern for my Vega.
I am not interest in the Classic 8 style nor any 13" wheels.
Staff (Barry Knickerbocker)12/11/2017 10:17:16 PM Thomas-
I am not certain that those wheels will accommodate a 4x101.6 bolt pattern.
I will not be able to confirm until the end of the week.
I will respond as soon as I can.
Thanks, Barry.Customer1/3/2018 11:00:21 AM Hi Barry,
Did you find an answer to my question?
I am trying to find some wheels for my Vega that look close to original in a 14" or 15" size.
Thanks,
Thomas
Customer5/9/2018 3:02:30 PM I am still interested in purchasing custom-drilled 15" dia. LeMans or Retro 4 wheels with a 4x101.6 bolt pattern for my Chevrolet Vega. Have you been able to investigate if this is possible?Staff (Administrator)5/9/2018 3:37:51 PM I believe that we can accommodate that bolt pattern, but we would have to use a small lug bore that would require the use of tuner lug nuts. Like these; http://www.ezaccessory.com/Chrome_Acorn ... p/2804.htm
If that works we can take a closer look.
BarryCustomer5/10/2018 12:35:21 PM Hmmmm... Vega lugs are 7/16-20. I didn't see the tuner lugs in the 7/16-20 thread in the link to the website you provided. OK. I did find them on ebay. would these be equivalent?
