You see, I took the Blue Funk's front end apart to KBS treat and paint it. When I went to reinstall the wheel cylinders, I believe I had to put the left wheel cylinder on the right side and vica versa in order for the brake line to come off of the cylinder according to the drawings I made.
Since I took apart the axle on a bench, it rested better upside down. I may have gotten confused in the process and I didn't distinguish the right from the left when I painted the backing plates.
If the '51 backing plates are interchangeable, I've got no problem. However, if they are not interchangeable, I may have them reversed.
Your assistance is appreciated. | | | | | Joined: Mar 2002 Posts: 9,115 'Bolter | | 'Bolter Joined: Mar 2002 Posts: 9,115 | If you look at the above link, for 51 to 54, there is only one part number for the backing plates. It also says that nthere are two required. Therefore right and left must be the same part. | | | | | Joined: Oct 2009 Posts: 419 Shop Shark | | Shop Shark Joined: Oct 2009 Posts: 419 | Therefore right and left must be the same part. Thanks for holding my hand and showing me the way, truckernix! Some things are difficult for me to understand and I need somebody to grab me by the ears and direct my attention. Just to be sure, I'm looking at; 1951-54 1/2 ton part# 3694867, right?
