hi,
they wont fit. Well they will but you need to have the center bored out to 98mm. Those rims are hubcentric. The other option is to run wheel spacers, 1.5" roughly, this will bring the center bore further away from the hub. Since you have the 2wd Amigo, its the same as a 4wd but no internals, same diameter and such, so you need to space the rim away from that hub as much as possible and you will run into problems with the center cap fitting if you are not far enough away. If you had a 2wd truck spindle, the problem wouldnt be as bad but still exists. Ive been trying to find NICE rims 17-20" that will fit my truck (2wd pup) but run inot that problem with the center bore. Most rims with the 98-108mm center bore have big ugly centercaps.
good luck
Ron
