I am in the middle of building a twin axle trailer and i am about to mount the 2nd axle. I plan to use the basic twin wheel plastic mudguards from Towsure.

Does anyone know the measurements of these, particularly the maximum spacing between the axles so that the tyres fit properly within the mudguard?

If anyone has this information then i would really appreciate it. Thanks.

Have a look at some of the eBay shops and stuff here
There's qwuite a selection with all the measurements.
