Hello Roger,
It`s fairly straight forward, i just accumulated all the MK 2 parts over time, and then all you need is the wishbone mounting brackets which you weld onto the chassis. They are available from Canleys and maybe other suppliers. Then it`s just a case of building it all up.
Only difference is the handbrake cables, it takes some careful setting up as the movement of the hub up and down affects the tension of the handbrake cable, but once setup properly it is fine,i would say better than before. I just didn`t want the 3 wheels on my wagon feeling again, or the 8 hour recovery from Cornwall.
I have another set ready to go on my Herald 1500, just done the Trunnionless conversion on that as well.(see Hub advice thread). Maybe i like tinkering.
Steve
