Ok got a standard au I,
will an xr6, c2r or ts50 front bar fit or if not what alterations must be done?
will the skirts and rear bumper fit without trouble?

Xr bar will fit with some slight mods, i think they have a extra bracket or 2,

But you need following
xr bar it self
xr head lights and loom
xr indicators

The xr side skirts and rear bar fit all series, series 1 came out with the body kit, series 2 and 3 only had the front bar it self unless it was a rebel kit, which has the rear bar and side skirts

Some one please confirm, not to certian

Ts50 kit will fit, but you need a series 2 or 3 bonnet as they have the big a** grill moulded to the bar

You can buy from AWC the ts50 front bar to suit series 1 bonnets and grills, it is a lil more expensive but you dont have to stress about it cracking where they are moulded together

C2r kit same as above, you need a series 2 or 3 bonnet for the grill to fit, but the skirts and rear bar will fit no problems

xr 2 possibly 3 did get skirts, nice subtle, clean looking ones.
not sure what it'rearbar was think that was plain though.
