5KCSTQ Dual piston calipers on '86?

["Graydon D. Stuckey" <graydon@apollo.gmi.edu>]

All,

	My other friend that owns an '86 5KCSTQ was over today to switch 
over some wheels.  While I had the fronts off, I noticed that he has the 
coveted dual piston calipers.  I checked his build date, it's 4/86.  Mine 
is 1/86, and I have the single piston jobbies.

	Does anyone know the crossover point for single to dual pistons?  
I am wondering if these were stock, or if the previous owner had them 
retrofitted.

	Thanks.
