John thanks..the models GM/Holden brought into Australia from Isuzu were very limited ..Jackeroo in V6 mostly 4dr, Rodeo ute and twin cab, Frontera [2dr was a 4cyl and 4 dr was a V6], ...I think thats it.. and the MU is/was a popular 'grey' import [diesel mostly]..the Impulse I never seen but looked at a quick review of it when it was in the US 90 - 92 and it got a good rap...so our parts 'bin' of cars is limited here
