Well you could do what we did before they made them, make them yourself. Use 1/8" thick, 7/8"x7/8" aluminum angle, 3/16" OD brass standoffs that are 7/8" long and some M3, M4 or 4-40 screws depending on the threads on the standoffs. The search feature is your friend, lots of us have made them before and posted pictures. I think Kabul Tankers build had some good photos, Mine too. You can get the parts locally and save yourself a bundle, not to mention only having to fix just the ones that broke and not tear down all the running gear.
