Will these axles fit?

Hi im just wondering if some solid axles out of a 1975 land cruiser would fit on my 87 4runner and what it will take to install..?

A solid axle swap is a MAJOR job. Land Cruiser axles are spring under you would have to perches etc. to make them spring over. The rear axle is offset not centered and wouldn't really be an upgrade to what you have now. A solid axle mini truck front would be easier.

FJ40 axles are also narrower. As said, they are spring under, and would probably require a cut-and-turn on the knuckles to get the caster you need.
