Terry,
I have a couple out back of the shop, will measure hub face to hub face & post tonite. All the ones I have here are CV / Solid shaft approx 1.25" dia.
One note of caution- while they are relatively inexpensive out of a wrecking yard, the reverse might apply if you have to overhaul one.May pay to check out some parts costs at your end. I have been paying around NZ$200.00( US$150.00 approx ) for the whole assy on local auction sites. Have enough now to see both the cobra & daytona out ( Along with me probably)
