The 200C is a 3 spd with lock up torque converter only. It is a lot smaller in diam, shorter, and lighter than the 2004R, making it easier to fit while using the stock console, associated linkage, and driveshaft angle. Don’t know about the Monster bell housing, but a stock BPO bell housing does NOT fit the 215. You need the adpt for a BPO bell housing. The reason to use the BPO housing is it does not stick up on the top mounts like the std GM housing, which makes for less clearancing of the tunnel and the trans housing itself.
