I was wondering on my stock style brakes on my 87 firebird formula what type of fitting and flare I would use and also I have switched to a moser 9" with rear drum and it requires you to run the GM 9.5" drum which I believe the years are through 64-81. The wheel cylinders I bought are from a 70 chevelle so I was wondering if anyone knows the fitting and flare required for this type of brake as well. Also if anyone would have a close up of this type of brake or a site where they show how to install its components that would be greatly appreciated. Thanks for the help.
