can't find seem any info on my 1970 jaguar xj6's differential. trying to find specs, if its a limited slip, just anything about it would be a great help

 

To find out if it's limited slip, put the back end up in the air and spin the wheels. If they both spin the same direction when you move one, it's limited slip. If they spin opposite, it's a standard diff. To find the gear ratio, mark the drive shaft and mark the diff. Count the revolutions and do the math.

 

ill do that today. thank you
