Alternatives to B4 CVA/CVDs

Hope this is the right place to post, I'm trying to find a replacement CVA/CVD set for my B4.2 and can't seem to find any in the UK. Every time I've ordered something outside the UK I seem to get stung on taxes or shipping is crazy expensive.
(I think everyone must have used them on their RC10s!)
Does anyone know if there is an alternative to the AS9599 or AS9677 sets?

I have been thinking that b5 and b6 parts might be suitable, but you need everything from the axle and hub: the axle, bone, hub, bearings etc. Since they use the same offset wheel, and roughly the same diff, the distance have to pretty much line up with some minor tweaks.

Thanks, I hadn’t considered that, in the meantime I’ve got hold of FTX Edge cvds. As the Edge looks so similar to the B4 I thought it was worth a try. I also needed the rear hubs as its metric.

Drilled the hinge pin holes in the arms out to 3mm to match the hub and then discovered the dogbone is a couple of mm too long!

Managed to remove some material from the hub so the inner bearing moves towards the outer and it seems to fit. Haven’t had chance to run it yet though.

Ran it for all of 2 minutes Sunday. Seemed ok, until the pin popped out and the CVD bone fell off!
Rookie mistake, they come pre-assembled and I didn't check that the grub screw was done up tight.
Unless I can find a rebuild kit, then I'll go back to the original dogbones. Or I could spend another £12 for a replacement pair!
