RB 25det or RB20det crank pulley

[Somers]

I am looking for a good condition RB20 or RB25 crank shaft pulley. Please call my cell if you have one, a bit of rust is ok, but no chips or bad nicks. I dont check back here often because of long work hrs.

Rb25 and rb20 harmonic balancers will be different. Rb 20 has a 3 spline for your belt drive and 25 will have 2. I don't know if this makes a difference, just throwing it out there though

I know they are different. I have a full drag race application. I only use water and alt. The rb25 is lighter than rb20.

Anyone??
