stay driver side drop get a hp 44 from any year ford from 68-77 and change all the outers to chevy . 10 bolt or d44 they interchange. i used 10 bolt on mine. you'll hafta drill out the hubs/rotors to match the rears. unless you dont mind having smaller studs/nuts in front. way better unless youre doing a major project like 92 sas. plus the driveshaft angle is so good you will be able to retain stock driveshaft. (ifs shaft) best years for frt end are 77 -79 with factory leafs including f-250.no 78-79 coil springers. they wont work. this is of course my opinion, others may not agree , but i researched it pretty thorougly before i started. ps the only 77-79 f150's with leafs are supercabs (ext cabs). the f-250 hp d44s are easier to find.
