3rd member swap

[prpseats]

I have got an 89 mazda truck. after re splining the torsion bars and a 2 inch body lift, I got larger wheels and tires, 235/75/15, wanting 30's. I was wondering if I could just go to a junk yard or some how find a 3rd member out of a 4WD mazda and just do a swap, to get lower gears. do you think it is possible?(axels, drive shaft,ect.) or is there a better way to go about this. thanks for any help.

Not too many people build the old mazdas, so most likely not too many people know about them. I had one before I decided to go ranger instead and I had always thought of just swapping in a 4wd toyota axle or even an isuzu rodeo axle (6 lug w/ disks) into it. Not sure on the stock gears in your mazda but I got a complete 4wd toyo axle lying around that has 4.10's in it. PM me if you're interested in the axle. Steve
