Your lift looks great, steve. I couldn't justify the cash for the kit, so i've tried making them from scraps on the modeling bench. It's easier than it sounds, look:
Here's a more recent version, that like most things i build, is about 90% done.
Literally, they were both made from scraps of bass wood, styrene straight and quarter round strips, some scrap brass, and wood furniture pegs cut for tires. Save your money and make them yourself, If i can do it......
