Thanks for the email I really appreciate it. i have just bought a used but in great condition 501X so decision made. I do not believe that it is a WE although it has had a lot of upgrades added ie alloy castor blocks, uprights, steering, sway bar kit , rear alloy wing stay and Aaarashi new un painted shell.
The only thing that it does not have is either a front one way or centre one way. I have read a few threads and am still not sure which parts I need as the 501x and 501x we appear different
Is this correct
