    Rated 1 out of 5 by from Please read. I bought this for a coyote swap in a fox body..the first thing you see is they mig weld and then they powder coat over all the weld spatter.Second thing is I could not get all the bolt started so I called AJE and the told me sometimes they move when they weld and powder coat..I should just bend it to get the bolts to start.?. Last thing.. I called AJE BEFORE I bought it and asked them if it would change anything in the suspension geometry and they told me no.As it turns out it was 1 inch narrow then the stock fox body k-member . I sent it back.
