If anyone running an aftermarket or a 75-79 Sway bar could measure and post their I beam mount dimensions that would be a big help, I'm needing dimensions for both to have my chassis tech lowering beams built so as to be capable to run either.
I need the distance the sway bar link bolt hole is from the center of the beam in top view, how far the hole is from the I beam pivot, the hole size, and factory brackets appear to be angled in relation to the beam about 30° to 45° I'm hoping someone can confirm.
I'm sorry to be asking to be spoon fed like this, but I've been all over creation, on the phone, searching the web, even lookimg under strangers trucks, and I'm not having any luck.
First off, understand that this is eyeballing a tape measure on irregular surfaces and around obstructions. These are approximations as close as possibly can be measured. Angle of incidence in viewing the tape measure also comes into play.
The dimensions are from a '77 F100 disc brake front suspension on my '69 F100 with a factory front swaybar from a '78 F250 Camper Special.
1.Center of I-beam pivot to the 3/4"-10 bolt hole for the lower spring mount/forward radius arm attachment/swaybar endlink bracket: 37".
2. Center of kingpin to 3/4"-10 bolt hole in I-beam: 6-3/8".
3. Overall I-beam length (end-to-end): 45-1/4".
4. I-beam pivot center to kingpin center 43-1/2".
5. Middle of I-beam between the kingpin center and the I-beam pivot: 21-3/4".
6. Hard to measure the swaybar endlink bracket angle on irregular surfaces but, comes out to about a 55° angle off the forward end of the radius arm, in relation to the forward surface of the I-beam.
7. Hole in swaybar bracket for mounting the lower end of the swaybar endlink is for a 1/2"-13 bolt.
Thanks Ultraranger, I know I'm trouble because my momma tells me so to this day
The hole in the bracket for the 1/2"-13 end link bolt, that's what I'm trying to figure out where it is in relation to the 3/4"-10 coil spring/ radius arm bolt.
basically I'm having brackets welded to the new I beams instead of hunting for C brackets and replacing my radius arms.
Straight-on view of the left side swaybar endlink bracket. --not my truck. This was on a friend's truck that I installed a disc brake front suspension on and added the swaybar endlink brackets, for when he finds a '75-'79 front swaybar, later on.
From that angle and from other pics I've studied it looks to be approximately 1 1/2" inboard of the center of the 3/4"-10 bolt when viewed from the front and 2 1/2" forward of the center of the 3/4"-10 bolt when viewed from the top.
