Hey guys, I am to the point where I am going to purchase a power brake booster/master cylinder/proportioning valve. I was going to use the brakes from my parts car but I want it to stay under the floor so I got to get a new system. I found a kit that has master cylinder, booster, and prop valve all together for $230 free shipping but it says its for a 53-56 model pickup...but it looks extactly like the 48-52 model they sell yet they are more expensive for the 48-52 models....and I don't know why. I am going to buy the trans crossmember that has the master cylinder mount made into it from chassisengineering so I won't need any brackets they sell where you can mount the booster to the frame.

 

You should call the vendors' tech line,or otherwise contact them.There are bound to be specification differences not apparent from a stock photo.
