granted but its easy to make a new front crossmember for the hangers, even if you don't have the means to make one, you can find already made ones.
a 110v mig of fluxcore welder can weld them to a yota frame and still provide enough penetration for it to be as strong as if you were to stick weld it. even if you don't use rears up front a desent lift would require either a new crossmeber or longer shackles
