Rear leaf spring options?

I busted a leaf and am thinking of getting something other than stock to replace it. do the 1 ton toyota leafs fit right in? I want more capacity than stock so. and i dint know if i should get some with a 3 inch lift and get spacers for the front? any ideas wowuld help.

 

I needed more capacity and decided to put in rear leafs from Hell Creek Suspensions (http://www.hellcreeksuspensions.com/toyota_page.htm)

They've been in about a year and are doing well. I had a truck load of brick a few weekends ago and it handled it just fine. It did raise the rear almost 2" but I can fix that with spacers or Billstein 5100's when I get the money.
