Replacing front leaf spring bushings?

[2_wacko]

My 1987 Chevy V-10 truck has a 4" lift but I do not know what brand the lift is. I believe its a rancho because it had rancho shocks. What part # or how ca I make sure to get the right bushings.

The best way is to take the bushing out & measure the I.D. of the spring eye. Be sure to measure the front & rear eyes as they prob are different sizes. (been there done that)
