Again a new part without instructions, not even a picture, when will it end!!!!

My question is, is there a gasket or seal that goes between the booster and the master cylinder before they are bolted together. Also does the brake proportioning valve get mounter to the same stud as the master cylinder? When replacing the the input shaft that mounts to the brake pedal assembly, there are two holes in the pedal arm, previously the manual brake input shaft was in the upper hole. When installing the booster, if I use the upper hole the angle of the input shaft seems wrong, do I need to use the lower hole?

Thanks in advance for the help and info.......

nope, no gasket between master & booster.....usually some type of bracket is used to mount the prop/combo valve, using a stud of the master , but, in my case, it wouldn't line up, so it just hangs there, with five lines connected, i don't think its going anywhere....i hope.....yes, to the lower brake pedal hole.....have fun!

Hi guys - Newbee here. (2nd post)
I did just do a '67 disk brake conversion however, and my kit had no instructions either and I know how you feel.
Like g-man said, I didn't have a gasket betweent he master and booster either. I mounted my proportioning valve bracket (supplied) on the wheel well side stud of the master cyclinder (to keep the lines and all away from the headers) but it was a tight fit and had to bend the bracket slightly.

As for the pedal arm holes, my kit had a bracket to mount the booster/master to the firewall at an angle which made the clevis line up with the lower hole.

Here are some of the problems that I had run into when doing my disc conversion on my 1970 Skylark. I didn't have nearly these problems when doing the same conversion to my '66 Chevelle.
