first off, that's not an MII front end, it's just a transverse spring, front end which is what most all T buckets use. as for the master cyl, you might want to rethink putting it on the firewall, it would be too close to everything, just wouldn't work. I'v never seen a T bucket with a firewall mounted master cyl, I don't think there is a kit to put 1 on the wall for the T. as for the floor, it should be fiberglassed in.
