Comanche Master Cylinder Upgrade

[huricane4]

What 1-1/8 or bigger MC would be a direct fit (besides brake lines)?

 

I know that Mercury Merquise will fit butt what year or part NR?

'78ish Grand Marquis with 4 wheel disc and hydroboost is the direct bolt in upgrade.  You can pick up two of the premade shot lines and just bend them and they will have the correct ends to convert from the Marquis master to the Jeep prop valve.

Seems that the hydroboost is rear drum?

That's the one I'm running.  They make a front disc/rear drum, front disc/rear disc and hydroboost front disc/rear disc from what I've seen.  You want the last one.  They supplied my rear disc/rear disc on my Cherokee nicely (3/4 ton Chevy rear) as well as the rear disc/rear drum stock setup on my '86.  They also supply the rear disc/rear drum one ton setup I currently have on my Comanche without an issue.  This was all with a single diaphragm booster.
