Converter lockup spring
 

I am installing a Superior shift kit, yeah wrong choice, into it now. The instructions for the converter lockup sayto use one spring for plug stamped 1, 2 or 3, use another for plug stamped 4, 5 or 6.
Question what do I do in one with the plug marked 8, leave it as is? The transmission came out of a 1992 Astrovan.
