Got my Keisler estimate

Part of my wanting the Kiesler was ease of install and easy fit. They come with a new crossmember now and all you have to cut is the hump for the shifter. Well, you have some cutting to do for the clutch hydraulics if you chose hydraulic over cable, and I don't know why you wouldn't. I am leaning toward the gear vendor, but I have heard of the GM 200R4 before. How does that fit? New bell housing I imagine. How about the splines?
