It is really simple to make them yourself. All you need is to buy some hardwood and use a dremel with a tile cutter tool and cut to depth and length as required for your application. A lot cheaper as well. Then use the nylon brackets to attach the gear as usual.

I usually after cutting the blocks to fit, install the 2 gear wires and then use 5 or 15 minute epoxy and place that around the landing gear.
