Do they fit?

My opinion
Installing Willwoods to get a 4.5boltcircle to run Chebby or Ford wheels, is ridiculously not cheap. Put the off-brand wheels on your trailer....... Besides plain chrome wheels IMO looks like Daddy is a cheapazz. And I get that, I was too; just don't make your daughter a victim; better to leave the stock wheels on there until you can afford something a little more up-scale.
