[V8] IC cold solder joints

[Jason Wilkerson]

Thanks,
   I love these cars too - I must, I've had two of 'em - 10 years / 100k miles worth.  I have done just about everything on them from Auto Trans rebuilds to timing belts and all the crap in between (including at least 15+ dash/cluster removals!).  Tonight I'm going to re-work the whole back end suspension and brakes.  Plus, I'm trying to get up the nerve to spend the money on the 5spd conversion!  Thanks again all.
