74 dart rear end in a 64 dart ,7 1/4 will it fit

They'll interchange with the following notes:
If they're both the small bolt pattern variety, include 5 lug nuts as the '64 may still have LH studs on the drivers' side. If the '74 axle is the 4 1/2" bolt patttern you have to include all the brake parts, lug nuts, and wheels. On both swaps, you need to use the old e-brake cables. They'll transfer from one backing plate to another with no problem....as long as you have 3 hands and 4 screwdrivers!
