David, there's a really good article on diffs in Circle Track mag this month.

In it, the experts say to keep your diff fluid below 250 degrees, because the

ring & pinion are tempered at around 300 degrees and the metal goes soft

after a while @ 300. Shouldn't be a problem to check yours. Keep in mind, our

ZFs have posi clutches that slip & generate heat so your temp will vary

depending on road straightness & velocity. For your winter project, consider

pulling your ZF, stripping it and drilling out the cast-in-place bosses &

internal passages for the factory diff cooler (rt side near speedo mount).

The smallblock GT40s had an oil cooler radiator mounted there w/ductwork to

deck scoops. Really looks trick (Note the ZF transmission was run upside down

in the GT40 & 'goose when you drill). J DeRyke
