Greg, master cylinder casting number is 64676593 08 ( could be Q8 ). It would be a direct bolt in as ports are the same as the original cylinder. I wonder if the different bores would trigger the differential warning system light. I have reinforced the pedal box. No one has mentioned Lockheed replacement servos. Thanks for the opinions so far.

I tried to post a reply yesterday and don't see it. My apologies if this is twice. The cylinder number is 64676593 08. (maybe Q8) this cylinder is a direct replacement. The ports all line up with the original. With different bores, hence different pressures, would my differential pressure warning light be on? No one has commented on Lockheed servos. Thanks for the advice so far. Gary

Hi,
With a stepped bore master cylinder the pressure will be the same in both circuits.
