Does any one know of an aftermarket disk & caliper style parking brake for a Dana 18 t-case. I saw one on a older cj the other day and it bolted up to the rear yolk just like the drum and had a bracket for the wilwood mechanical caliper coming off the rear bearing cap. Looked really clean for a homemade job. The owner spoke little english and was not happy with me inspecting his rig. If anyone has heard of this let me know.
