need flexplate: 1978 351W mated to 85 AOD, where?

I used an AOD flexplate no problem with a C-4 so the reverse should hold true.All 351w's are 28 oz balance, 302's changed in the early 80's but 351w's stayed the same.The 28 oz balance is also shared by 289's and 351c's.A cheap place for flexplates is Bulk-part.com if you don't need an SFI one. http://www.bulkpart.com/Merchant2/merchant.mvc?Screen=CTGY&Store_Code=2&Category_Code=FLYcatalogFORD
