i think you have to measure the bore of it and get one that matches this guy did the swap in his truck to a 1 ton master post # 203

alright well i re bench bled the master put it back on still nothing, i read about switching the lines on the ports did that still nothing. So im thinking maybe my 8 month old master is shot maybe a seal went in it from sitting over the winter or something who knows. i got another stock ranger master from my friends im gonna bench bleed it tomorrow an put it on to see if that helps. Does anyone think it could be the brake booster? loosing vacum when its running or would the motor die from the lose of vacum. the idle does fluctuate a little bit when i hit the brakes a bunch.

If its easier to push the brake pedal when the engine is running vs the engine is off, then your booster is working as it should...The MC sitting for a length of time would be a good reason why its not working, the seals could have dried up and gotten brittle, breaking when you applied pressure to use it (if it was empty)...

as far as i know the master never went dry while it was sitting over the winter, it may have when dry over night when i took the lines off but i re bench bleed the master an no air was in it. But well see im gonna put the other master on tonight an see what happens
