Default Need another measurement please!!

OK, I asked about the front LCA's, now I need to know the height from the ground to the rear LCA inner pivot bolt with vehicle on ground and loaded. Also, the rear lateral links (I'm a Mazda tech, thats what we call them, LOL), what is the angle between their front pivot bolts in relation to rocker panel (or ground) and is the lower parallel to ground or inclined? I know how far apart they are, have their bracket, just need to know the mounting angle. Can anyone help?

What year?

I think there's probably a little variation from '84 - '96...

The suspension I have is from a '96, going in an old Dodge truck. Thanks!

What are your tolerances?

Even if someone can measure their own for ya', you might not be able to rely on their measurements. Are these specs even in the FSM?

I'm trying to keep the stock Corvette geometry. By knowing the lower inner rear control arm pivot bolt location from ground, lower lateral link front pivot height from ground, and center of tire height (I believe the C4's use 26" tall tires, so 13" at the center of hub), everything else will fall into position. I just have to modify my frame for the ride height I want. I would feel weird crawling around under a Corvette in a random parking lot, ha ha.

Is this what you're lookin' for? It's a '94...

6". Give or take about 3/16ths, it's gotta' be close to spec.

Post a few pictures sometime.
I put the complete C4 suspension on my '51 Chevy pickup a while back. The '92 rear trackwidth is a touch too wide with the wheels I'm using, so I'll be putting in a set of '84-87 rear spindles/knuckles in the future to narrow the track an inch or two. Next step is to finish the recessed firewall and wiring issues. Looking forward to getting it on the road once I finish my '69 w/C4 suspension transplant currently in progress.

Not sure I understand your question. I put the C4 suspension on the original frame of the '51 truck in the picture, and also put a C4 suspension on the spare '69 frame (bottom two pictures) for my '69 Corvette.
