It's a shame that the folks at Gear Vendors have never offered .67 or .70:1 ratio unit, Their "gear-splitter" .80:1 ratio works well for that but isn't enough of an overdrive to justify the cost, in my opinion.
It's compact enough not to require the major surgery to the floorpan and crossmember required to get an A-500 or A-518 into an A Body.
I keep hoping they will change their minds, but they don't seem to be going in that direction...
