what to do ?????

have some rims that dont fit the brake drums rim's are 16 in spoke A wheels and drums are F100 and the rear drums are a 8 IN ford what can I do I want to run those rim's

 

cut the centers off some kia rims and weld them on to the rims you want to use!
that all ways works.

 

adapters?

 

You need an adaptor that fits inside the empty space between the drum and mounting surface of the spoked wheel.

 

check with Rally America, wheel vendors here. They likely can help come up with the answers to your situation.
