if you cant find a c4 blockplate and dont mind cutting a hole in your t5 plate , the t5 block plate works perfect for the small bell c4. just have to cut an opening at the bottom so you can get to the converter bolts. holcomb motorsports used to sell the shifter conversion kit,(dunno if they still do) it came with a 1/4 stick and the mounting plate to put in the stock location. was somewhere around 200 bux i think.
