I have a new 4x4 box so all I need is the sector shaft for cross over. I know there are different types and I need to know which 1. I have a 90 blaze.
 
The two kinds are variable-ratio and fixed-ratio. It's kind of a tossup, but I imagine most Blazers and Burbs have the variable ratio, and the low-optioned pickups would usually have the fixed.

Doesn't matter what year you get it from, 73-91, as the differences in those years are box (actually fitting) related.
