OS Giken Gearset - Any visual difference to OEM gearset?

[LifeIsFantastic]

Hello

I picked up a project car that which has a transmission that apparantly is an OS Giken gearset in S14 housing. I am selling the transmission, and I just want to make sure that I am making an honest sale.

If I were to pull the transmission apart, is there any way that I could tell if the gearset + imput shaft are actually OS Giken?

Thanks
Have a peaceful day

They are quite beefier, yes.

There are more than 1 osgiken kit though, one with only the first 3 gears, one is a full 5 gears set. Input shaft is an option too.

Ok, thank you.

Yes, I know of the different sets of gears and the input shaft.

- Has anyone been down the OS Giken path before, and have any reference pics? Aside from being a bit more heavy duty, do they have any stampings? I just have never seen up-hand the OEM gearset before to compare it to (I've seen pics, yet it wasn't clear of any OEM stampings).

-Does anyone know the specs for the input shaft, so that if I measured it I would have something to reference?

Thank you very much, and any help is greatly appreciated.
