Need reroof tips 1971 double wide parkway

My roof is leaking and has rolled galvanized metal roof. I plan on installing 4x8 sheets of osb on it then tar paper then rolled roofing. I need to know what the specs. on the rafters are on this home.I know they are 16" o.c. but that's it. Need to be sure they will hold up to 1/2" osb and rolled roofing material without my 2x3 exterior walls sagging. I have to do the work myself cause barely can scrape enough money for that. Does anyone know what size lumber was used on this mobile home roof for the rafters?
