Well this is Moparts where guys can't seem to bolt in stock parts without some level of problems...now if you happen to take your car to someone and bolting in a Borgeson box in is outside their comfort zone you might want to look for a new place to get work done....by some miracle there likely 1000's of these on the road in classic Mopars at this point.

I have purchased from Peter at Bergman Auto before and had no problem getting ahold of him by phone or email to discuss any concerns.
