It has been a while since I posted, well since I worked on the truck either, but last night installed the Master Cylinder and booster and it was pretty much a plug and play situation. Did not need to modify anything other than drill 3 holes. I was amazed how well it went into place I thought it would be a nightmare and it turned out to be probably the easiest retrofit that I have done.
Although the setup was bought from American Classic Truck Parts it actually was dropped shipped from CPP. I have to say I am extremely pleased that I did not need to modify anything this time around. Now I just need to run the lines and I should have brakes again.
