Hi
We have built a few chassis for shepherds huts, and horse drawn carts, I have attached a picture of the last dray we built for two shire horses.
I have drawings to enable land rover hubs etc to be converted to straight axles, we can also get hold of the correct turntables for the front axles.
As this is part of my business I am not sure if it is against forum rules to offer services so you may want to PM me we are based in Alton Hampshire not to far from you. So I am sure we could help out.
