Hello Rob from the Netherlands, thanks for reaching out. We do not have a digital drawing with dimensions of the Lippert Electric Trailer Brakes # LC66WD that I can send. I can tell you that these brakes are basically identical to the 3,500 lb brakes. The brake shoes are 10" diameter by 2-1/4" deep and the backing plate uses 4 bolts. If there is a specific dimension you need just let me know and I am happy to help if I can.

Hey Rob, did those measurements for the Lippert electric trailer brakes help you with your setup on the GMC Sierra? Your update could make it easier for others working on a similar conversion.

@JesseM Hello Jesse, Thanks for your response, but I stopt the project not enough info. If I want to do this I need to buy the brakes en make it work, than they have to pass the Dutch regulations, this is not easy. We have to much rules here, I need it write on paper first.
