Thank you Tech,,,,,you provide so much info.on here I started to say,Sir Richard, but I won't seeing how I don't know if you'd like
that or not,cause I don't want to get on your bad side.

But after viewing that link I still can't determine if the rear is an 'open' or 'limited' slip. Maybe all the truck rears are the big L? Anyone???
AAAAnnnd, although I was getting the F-100 ready for paint and selling it,now I'm tempted to put the 9" in the S10,which I bought to make a 1/4 drag truck. And I really can't afford to have it narrowed,new axles,etc.,etc., the S10 has the despicable 7.5 rear. OH,OH, how do you get this racing stuff out of your blood?
