I ordered part MB2099 (2 4"speakers with bracket to replace single 4x10 in dash on 68-70 B-body). The part does NOT fit due to heater control interference. I modified the part in several unsuccessful attempts to make it work. I understand I cannot return a modified part, but this misadvertised as a replacement part and I expect a resolution. I had to make my own bracket in order to fit the speakers to the dash. I have emailed them 3 times with no response. It's funny, because when I simply wanted to change a different order, they were responsive. Now, no response in several weeks. Classic Industries, if you are reading this, which I assume you do based on your responses to other threads, my order # is 12989257. I will not be placing any more orders with your company without a resolution. The first pic is the bracket I made, the second is the one Classic sold me that I modified. Sincerely, Patrick An increasingly unhappy customer.
