So I am very ambitious (do all my own work) but lacking knowledge beyond the service manual.
I am weighing my options. I am needing to spend money on my truck and thinking upgrade is the way to go. I am needing axle overhauls, shocks and cv's. so going to try and make the switch to a solid.
Now the problem being I am in the great white north and toyota axles are few and far between. I have found a land cruiser wagon, the body tells me it is and 60 series, the vin is JT3BJ60V0B0003248. I can not find info on diff ratio's. Do i need both front and read axles? should i thake the drive shafts if they are straight? aside from a trailgear 5"hd sas kit what else will I need to source out? Will I need a long slpine drive shaft? if so is that something i need to order or can i get them at a wrecker?
