I read somewhere on this site that a posi 7 1/4 existed. I was at the junkyard this past weekend and noticed a barracuda siting on top of another and out of curiosity i spun it and both sides turned, does this tell me that its a posi rear end or am i hoping thats what it is?
Also, what years/models did they come in? Im putting a 273 commando in my 63 valiant and figured this would be an upgrade? from what i have in there now, it should bold right up from what i gather but not 100% on the driveshaft.
Thanks,
Jake
