'92 XLT, 3.0 ltr, AT, 2WD. Your basic work truck.

I just noticed while under the truck yesterday, that my right spring has a split running half the length.

What are some options I may have in replacing it? I'm in Mexico and I may have a problem in finding a used one. I might be able to have my sister, who works in AutoZone, send me down one.

I've never liked the fiberglass and would replace with leaf springs if I had a good direction to go in.

Thanks
