i have a 92 B2200 and i want to put a toyota rearend in but i dont know if i have to change anything big or if it still bolts up to the leaf springs, any info would help thanks

Why swap unless u r trying to get a different bolt pattern?Mazda rears are very sturdy and reliable. Never known 1 to fail. They are geared low (3.9 to 1) but otherwise are very serviceable?BJ

well my seals are leaking and one wheel is not streight and i was told i could put wider tires on, plus its aftermarket haha

I think there is a thread on Mazdabscene.com that addresses Toyo rear end swaps. BJ
