Frame datums

[RustyRage]

Does anyone have a good location to align front to back and side to side the front suspension? I am installing a new "after market" suspension and I took measurements, pics and documentation but I am finding out that the fixed point I used offset from each other. I need a solid fixed point on both frame rails to measure from. Thank you for the help.

Is the rear axle in place? Can you measure up from that? That is what really matters, that the front wheels are lined up with the rear. If that is too cumbersome, possibly you could find some holes or points up front that do line up and measure equally with the center line of the rear axle. Then you could trust those new points up front.

How will you locate those points sir?
A plumb bob is the closest I can think and that may be tricky
You might find an engineer of sorts and use some trig on it?
Good luck either way man, maybe someone else will have a better solution, more than just a few of these folks have used and re-used those same frames on racetracks

There are keyholes in the frame near the rear..... spring hangers..which are forward of the axle
