Replacing rear CV (driveshaft) axle for first time - any alternatives to ordering an OEM split pin/cotter pin

[r3moted]

I have a brand new rear axle for my 350Z but struggling to find   a non-oem split/cotter pin anywhere in the exact size.  The OEM ones take 2 weeks to ship which is a bit long. Does  anyone know  where  I  can get a split/cotter pin that will fit properly? Does it need to be the exact size of 4.78mm x 50mm. Any recommendations of places I can ideally buy from tomorrow would be ideal!

Thanks

I got mine from Amayama because I couldn't find the dimensions anywhere but I measured it, I'd look for cotter pins assortment kit but make sure it's stainless steel and not plated, looks like M5 x 40mm apart from the short leg being bit shorter than the standard dimensions
