What year is the rolling chasis? Is there a possibility that a non Ford or maybe mod motor was used before? I have seen some funky K members when people put GM motors in Fords. I don't think that is a UPR K member. I have seen the UPR K members out of a car and I can say that I wouldn't feel comfortable with it in my car, so that may be a good thing.
Cant tell what it is, but it is not:
Steeda Qa1
UPR
Maximum Motorsports
Griggs Suspension
