We had one made from a picture. Now it worked fine for all the Waukesha engines. At the time we had it made the 20-2150 had not been introduced yet and the only engines we worked on were the Waukesha engines and we got along fine with it. Ours was not adjustable for width which it did not need to be for what we were using it for. We also mounted a couple of hydraulic units on it.
