hello everyone, I was just wondering what the stock size booster was for a 71 with power brakes? was it an 11 inch?

any insight would be great!

Thanks!

I am at school at the moment but I found the booster on napa's website and the diameter it mentions is 10 3/4"
Here is the link:

I do not have the booster. Will there be mounting braket or placement to bolt to already on my truck. 71 also

You would have to pick up a bracket from a salvage yard and the mounting holes might not be there if you only have a master cylinder on there. no to sure though. I believe the best or only bracket to go with is up to a 72'.
Hope this helps somewhat.....

Yes, thanks, I suppose it's easy enough to look for holes where the braket would mount. If not it would be a trick to get exact for everything to line up?

You will also need the rod to the pedal.I can't remember the exact issue but there is a difference.Maybe someone will add info.
