I need to replace the master cylinder on my '94 w/ABS. Advance lists two MC's, a 6.5" and an 8". Car currently isn't on site to measure. Anyone familiar with the size I need?

Also appreciate any tips if someone has done this job. I'm a little nervous about bleeding afterwards and if I'll need a Tech 2 to finish the job. I typically bench bleed before installation.

My park avenue and my dad's 2 lesabres all have 6.5 in master cylinders. I'm not too sure what the 8 inchers are for and/ or if they'd make any difference in fluid pressure.

Thanks Loekee. I'm going to drive the car up to the parts (Advance Auto). They have both sizes in stock, I'll eyeball each.
