Emery as you saying they can be cast with the mounting side having move depth to the cylinder? Were not talking the total thickness of the mounting boss just being thicker meaning the studs in the booster are to short.....
Emery Stora wrote on Sun, 07 June 2020 15:22Either of those will do. Just measure the thickness of the bolt flanges. If the new ones are thicker it will require a longer push rod. If thinner you’ll need a shorter push rod.

I buy a ton from amazon. I have found them to still be pretty accurate with dates. Especially if you are a prime member, which I am. Good luck!

The trick lately is they want you to buy it then they will email you a delivery date or the delivery date is 6 to 14 business days even if you have prime.....always seems to be things they may have to bring up from the US warehouse or something. As it is its taking 3 to 5 days to get something from Toronto to my house (i can drive there in 3.5hrs)

When I replaced the master cylinder on my GMC, I had a friend who was a very experienced tool and die maker machine the extra thickness off the new master cylinder.

I took off the MC and I'm bench bleeding it, the front circuit now seems to move fluid as I push the plunger, but the rear one, (to the front brakes), only seems to start moving fluid after I push it in about 1/2". Is this normal?
There did seem to be some air in the MC, so I'll put it on and give it a try later.
