14 inch tire help wanted....

I found these 23 year old Cragar S/S rims in a friends barn and he gave them to me to free up space. I washed them up and polished them and you can see the before and after pics. I plan to use them on my 1972 D100 1/2 ton pickup. A problem I am finding is that not many tire companies make 14inch tires in a wide variety of sizes. The rims are 14X6 and 14X8, and I want tires wide enough and tall enough to fill the rear wheel wells of the truck. I have found L60-14 Mickey Thompson Indy Profiles for the rear with F70-14's for the front. I would rather have radials but cant seem to find them. Can anyone help?
