I got mine from this seller if I recall correctly:
https://m.ebay.com/itm/8-INCH-FORD-T...from=R40&rt=nc

If that link doesn't work for some reason, the seller to search for on ebay is: tj1141

Can't remember exactly what I paid at this moment (need to be at home on my computer), but I think it's gone up a little since I got mine.
