I was told that I could put a GM 10 bolt derect swap in place of the back rear in my 86 4runner (springs and all) is this true? If so any suggestions for a front straight axle conversion besides using an older toyota one. I am planning on installing a rather strong v-6 or v-8 for playing in the mud and would like to feel safe with my rears. also open to suggestions on the trans and transfer as well. Motors will be GM
