Any of you guys have had a driveshaft made up. I need the name of a shop that does datsun driveshafts.

The good shops can find the specs or just take measurements. And there are aftermarket propeller shafts out there. Nissan calls the center longitudinal shaft propeller and the two "half-shafts" drive.

You need to be aware of one big problem with 1975 though - Nissan used a unique flange bolt pattern on the differental. 76, 77, and 78 won't work on a 75.

Motorsport Auto (TheZStore) knows, on their Replacement page. But not on their Performance page. Oops.

Don't buy a Performance shaft from MSA.

Do the half shafts in 1975 have replaceable ujoints or are they stakes like the driveshaft?
