I got my 63' drag bug on my car trailer and the bottom of my door hits the fender of the trailer. This makes it very hard to get in and out of the car when loading and unloading the car. One solution would be to cut the fender of the car trailer. Another solution would be to make the doors removeable with some quick release pins. Please let me know if you have done this modification; where did you purchase the pins, and what did you use for the quick release pin?
