Import Auto Supply - Quality you can Trust

All My Pictures are of the actual part you are buying in most cases and not a file photo. I have been in the Import Auto Parts Business for 45 years.  I sell nothing but high quality Import Car parts and know the differences of what Quality is and is not. Check my feed back on E-Bay. See my 4 shipping options for best service.

Fed-Ex International Shipping now available on request.

I do ship Worldwide.  If you need shipping estimates. Only you can see what it costs on your end. When you use Buy it now and E-bay sends you to the next screen that will give you the shipping options and prices before you check out. At that point you are not committed to buy until you click on the shipping option you want and you finalize.  DHL you will have to E-Mail me your request and I will give you a price. I will need the address and postal code & country. It is usually less than Priority Mail. E-bay does not give an I-Con to offer DHL So I have price it myself. IA-27615/89142
