Thanks for the help, I have an axle and springs, so I am really looking for the dimensions so we can be sure that the balance is correct, for (hopefully) a smoother ride for us and a smoother pull for the horse. PaladinCentaur, those are good websites, I am sure I can find a blue print on one of them. Thanks.
Minis5772, The ones I have looked at on Craigslist are not well made or they are very expensive or both. If I come across one well made that I can afford I will buy one, If not I will continue with my project
. I also know that this won't be a fast project and I am in no hurry, I will do the research and build a safe nice one or come across one I like (safe and well built) and buy it, or (sigh) I'll just have to suffer and keep riding
. I guess there is always a silver lining. Thanks again ya'll
