All I meant by "dry fitting" was I was going to set the cylinder (not assembly) in the mount and see if the angle of engagement between the cylinder and the push rod while connected to the brake pedal would be suitable for use, however, I have recently found a master cylinder for this car specifically, but thank you all very much for getting me headed in the right direction, as I had said before, this is my first restoration, and I'm sure I will be back on the forums again for more inquiries, thank you all again

After doing more research I've determined that this master cylinder I have is off of a 1936 Chevrolet. It does have the same bolt spacing as the one for my 36 Buick, does that mean I shouldn't have a problem using this cylinder with my car? Or are there other aspects I need to take into consideration such as the bore size or stroke length. EDIT: i decided to try and dry fit everything together with this master cylinder and the major problem i had run into is that the cylinder needs to be lower in order for the push rod to have a mostly horizontal stroke. so i could either drill new holes in this bracket i have that mounts on the transmission housing, which would be very, very difficult because where the cylinder would need to bolt to happens to be the same place that the mount attatches to the transmission housing (shown in picture), and my second option is to find a new master cylinder with the mounting bolts coming out of the middle of the cylinder. i hope my pictures help a little bit with illustrating my problem. the 3rd image shows the cylinder in the mount correct way, and im holding the push rod about where it would be sitting if attached to the brake pedal.

After doing a bit more research I've found that the correct master cylinder is 1-1/8" Dia. Rather than this one which is 1-1/4". And another problem I would have if I were to try to use this master cylinder is that I have absolutely no information on it, I don't know what car it's from, nor do I know what rebuild kit I would need for it, not to mention the core quality is quite poor so I would have to get it either resleeved or honed

do you have any recommendations for finding a master cylinder other than spending 150$ on a new cylinder for my car specifically?

unfortunately, the link for www.oldbuickparts.com did not work for me, however thank you very much for the help

i have recently taken over the restoration of a 1936 buick roadmaster after my grandfather had passed away working on it, unfortunately for me he was not a very organized man, and after going through all of the stuff he had scattered all over the place, i think i had found the correct master cylinder for this car. this is my first restoration job i've done and i havent been able to find hardly any info on this master cylinder and i'm not even sure if its the correct cylinder for this car, if somebody more experienced with this could lend a beginner some helping tips id be very grateful.
