how tall are the runners? I want to try making one.

They look to be about an inch. I thinking of making runners out of 1/4 in. aluminum stock and about 1.5 inches tall the welding an aluminum plate to the tops of the runners to hold them in place. pretty much like an aluminum HV3. Of course I would do some research to find the optimal length for the runners just using 1.5 as a ball park figure.

well i got a very bad reply from zzperformance they say they lost money on this sales they will replace it if a pay to send it back to them i think this is bad for bussiness to sell bad quality and not give sastisfaction to there customer
