Use the F-body aluminum master. The truck master has too large of a bore when used with stock, passenger car brakes.
The adapter thickness makes up for the difference in master cylinder design. You do not need to modify the original push rod.

OEM 2-bolt aluminum master cylinders with plastic reservoir:
'95 Lebaron 7/8" bore**
'89 Dakota 15/16" bore**
'85 Diplomat (F-body) 1 1/32" bore*
'85 D-150 1 1/8" bore*
**Back of piston must be bored to accept manual brake push rod and retainer.
* Back of piston will accept manual brake push rod and retainer.
Rule of thumb:
1. Master cylinder piston size is relative to caliper piston size. Large caliper pistons require large MC piston.
2. All things equal, smaller bore master = higher line pressure and longer, softer pedal stroke.

That is why I use the big bore.If you use a lot of braided line the pedal will fill like a soft grapefruit.

Just to clarify:
The 85 diplomat is a "M" body no??
