early 944 brakes, stock MC....dosent feel right

[super vw]

Well, i just got my hands on a early 911 (73 targa) MC. i mounted it up, but have not plumbed it yet (still waiting on parts). it bolts right in. i think i is a 19mm?

anyways, i will give this a try to see how the pedal feels once i get it plumed up. If this dosent work out. i will try to find a used 944 MC to try. i want to find the best "bolt on" option, and it seams like a lot of porshe stuff shares the same mounting holes.
