Does anyone know what Z those cvs came from? They look a bit long for the 280zxt's, Im thinking of the z31 NA cvs but Im not sure, could be z32? The reason I ask is I want to source the bolts for the cv to the flange. Thanks

They LOOK like 280 ZXT half shafts. The flange bolts are probably 8 or 10mm metric. You can probably get them at any hardware store.

The 300ZX NA shafts and 280ZXT shafts look very similar. The problem is that the 300ZX NA shafts are way too long to fit in the car. There is a guy on HybridZ who talked about cutting them down and resplining the shaft. I'm a bit wary of his measurements, but it would be something to look into if you were putting these in an S30.

Thanks guys, I'll confirm after when they are here. As for the bolts, should I order them from Nissan or any high tensile bolts will do?
