ryan, i am in the middle of doing my d44 right now. i got a ford service manual off e-bay for about 10 bucks. very detailed. its year specific. the one i have is for 1990. it includes broncos, f-series, and vans. covers 8.8's, dana 60's, 10.25 etc. two very thick brown books. best finds i have. no comparison to the hanes or chiltons.
