transdapt motor mount issues.

hey guys, ordered a set of transdapt engine mounts to convert my 273 dart over to a big block, they showed up yesterday and i am kinda confused now. i ordered pt# 4698 and 4697 showed up instead. i assume the 97's are for a /6 to BB swap but reading the instructions they say in the first page that 97 is for a /6 to BB swap and the back page says its a A engine to big block swap.

so in 4 pages they swap the part numbers. i have posted a pic but i assume the larger mount is for the /6 k member.

anybody know for sure?
