(re) locating the rear end
Ok, I'm planning on converting the leaf rear of my '54 to a 4-link and I'm trying to find the best way to make sure that I get it back in the correct location.
Tell me if I'm crazy, but here's what i'm thinking. I've been taking a million measurements with the frame level. My frame width is consistent from front to back, the height to the ground is consistent, and my diagonals are right on so I know the frame is straight and square. From what I measured with a plum bob, the rear axle is located directly under the snubber mount holes. Does it make sense to make fixtures that cradles the rear end and has a pin to locate it in the snubber hole? This way I can set the frame down on the rear end and weld the 4-link brackets in place. Does this reasoning make sense?
I would love other suggestions or predictions if this will work. Thanks

Svooom, sounds like you put alot of time and thought in to this rear end mod with measurements and all, and not ever done it myself, i can only offer my opinion on what i might do. First i wouldn't move your frame since you already have it level, 2nd i would call the company you bought the suspension from and talk to a tech, he will most likely be able to put you on the road to fewer headaches. let me know how you made out i will be needing that info my self. sorry for the lack of knowledge, your friend fever

I agree with you that you want to properly locate the rear end but by virtue of using the 4 link system, you will likely get adjustment built into the links. So then you want to be most concerned about keeping the axle square to the frame and cenetered side to side. i plan on mounting a Mustang 8.8 with the triangulated links, I will try to position the axle on some axle stands that allow a bit of rotation, locate the center line off the snubber with a plumb bob to each side of the axle. Then with identical lengths of links, position and weld the mounts to the frame.
Does any of the above make sense.
