Good thing a direct line to the manufacturer! Please keep us informed , maybe a " special order for evaluation of different wheel sizes for RWD and FWD " making up a min order for your business that retails to a small market here of Volvo enthusiasts ( meaning us on this site....he he ) , it works for small items , why not bigger ??
It may be worth looking at
http://partsforvolvosonline.com in the UK , we have members here from UK and i have family but they do volvo parts similar to IPD et al and sell IPD stuff but postage to here is usually cheaper....
Maybe an aggregate of Swedish and other Euro volvo part sellers to be shipped from the UK would be better , they make all the best stuff over there and ship it to USA anyway!
Keep us informed ?
Pics of your mates collection of cars are a requesite here i think , too many jusy ones there not toshow us
