Wanted - SA Urgently - driveshaft

I urgently need a driveshaft for my racing buggy... I am supposed to be racing on the weekend, and broke a driveshaft recently. I just found out that the replacement I had in there does not have enough movement 🙁

the one I broke has overall length about 475mm, but the spline on each end is roughly 55mm long, to allow the CV to move further inwards than normal.... the replacement I have only has a short spline, but is the same overall length.

I've seen these used on a few buggies, so thought people might have some idea where to get them?

I would get one made, but can't get one done before the weekend 🙁

any help ASAP grealty appreciated 🙂

cheers
