23 T Bucket?
For a Corvair box it seems there are 2 ways to find one. Either find a whole Corvair to buy or e-bay. I scored one on the bay for $55 a couple of months ago. Guess I should have bought a bunch of 'em when they were a $15 to$20 item.
I have heard of a reversed Vega box but haven't seen one. Might be a good alternative. I would think there might be some clearance problems though. I just looked at the one in the shop. It's twice the size of the 'vair box. Might work for a cowl mounted box though. Have to look at that possibility closer.
