Hello everyone!

I'm new here in forum, but I really need your help. We bought a race car, with H22A swap. When we bought it, driveshaft axle just got broken, so we used original driveshaft axle from B series honda crx. It fitted well, but my question is, that the only driveshaft axle that could fit? I find B series original driveshaft axles to be very expensive, and I'm sure there is some kind of axles that fits well too. Maybe someone who knows, could help us out? We already tried the Tegiwa B series driveshaft axles, they are too long and doesn't fit.
