Hi Jared,Was talking with Andrew here in Ak yesterday, he has BW35 and BW45 gearboxes from a Hunter, is willing to sell. The BW35 is stronger but uses a cable operated control, not rod as on the BW45.andrew.shaw@progressive.co.nzBTW the H tab in your rear brakes is necessary to keep the handbrake lever travel within limits and the leverage angles correct, otherwise too much free play at the handbrake lever and a poor handbrake.Pretty easy to make them out of scrap steel.CheersRoss
