If this is intended for a 1965 GT with front disc brakes my review is as follows: Spring is too short for the larger GT master cylinder, online picture of the components doesn't match the product I received. Service, delivery time and customer service were great.

I’m not sure this will work for my K/H disc brake master cylinder. The parts don’t look the same, and the valve broke while I installed it. This is not my first rebuild so I know the proper procedure. I do have pics showing the differences. For some reason I can’t post them. I ended up using some of the kit. Thank god my rebuild kit from 1991 was still usable. The spring is too short & the pistons secondary cup is different as well as the piston. I did use the new snap ring and primary cup. I won’t be able to tell if it works until I mount the entire system (that’s not happening soon). I would recommend only as a last resort if one can’t find the original Raybestos MK493 what’s crazy is the shipping cost doubles the price.
