An '89 Dakota has a 15/16" bore alum M/C but I do not know if it has the recess inside the rear piston recess "thimble" which is REQUIRED for a manual brake app. An alum M/C has either a thinner flange or the piston is closer to the flange (#2 iirc) which will want a shorter pushrod but the adapter moves the whole shebang forward which makes up for some (or all) of that distance. With the right (with the recess) M/C I would mock it up & go from there. There are several lengths of OE manual brake pushrods available

My Dr. Diff kit worked great with my original manual pushrod. Did not even need to adjust to make my brake lights work correctly.
That is the way it is designed to work!

Unfortunately, no off-the-shelf, 15/16" bore aluminum master cylinder will fit a manual brake application.
As far as I know, I'm the only source for the master. I'm currently out, but the machine shop is working on another batch.
How come on your website it states for B/E only?

On this note, why not just run a 15/16" four bolt M/C? Other than the slight weight savings I don't see the benefit of the 2 bolt setup. I did check out Rock Auto to price a 4 bolt unit, about $30 for a new Raybestos Professional one.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

As far as I know, my website lists A, B, and E body applications:
* 4 Hole for all A-Bodies and B/E-Bodies w/power brakes
* 4 Stud for B/E Bodies w/manual brakes
Exactly, why no 4 stud for A-body with manual brakes... why is it different than B or E?
