Well to answer you question even if it is a little late. Yes we do all sorts of custom fabrication. As far as how much and how long...For this particular job we would like for you to come in and sit down with us for a detailed evaluation and estimate. I know you said you found a shop in Minnesota that does it and if you get that information then we can get a good idea of what is entailed. We then could see if there was some savings to be had for you, and you wouldn't have to ship the car off to the great white north! Give us a call or just keep us posted, we would love to have the opportunity to do this job for you.
