UMI rear sway bar 70 Malibu

I bought an umi setup a while back. FINALLY getting around to getting the trailing arms on, and it came with a rear sway bar. Is there some trick that I'm missing. The holes closer to the front of the car line up fine, and when I get it tightened , the rear holes are about 1/4 inch off. Any suggestions or knowledge I'm missing? Calling tomorrow if nothing here.

Re: UMI rear sway bar 70 Malibu

Keep the bolts loose until you have them all installed and the nuts started, then tighten them up. Mine went right in with no issues at all.

Re: UMI rear sway bar 70 Malibu

Its possible you have lower control arms that weren't originally boxed and drilled. Previous owner may have drilled the holes incorrectly.

Re: UMI rear sway bar 70 Malibu

You could just go purchase some slightly longer bolts. Could you post a couple of pictures to give us a better idea of what you are dealing with??

Re: UMI rear sway bar 70 Malibu

They sell shims if the bar isn't close enough to the LCA, if you pull them in your bending the LCA's

Bought that and this.

Rear sway bar doesn't bolt up. I got in touch with the UMI rep on here and he sent me a measurement diagram. When I get off work tomorrow I'll get pics and measure it up.

One thing is there a different bar for boxed trailing arms vs tubular?

Re: UMI rear sway bar 70 Malibu

Not that I know of, the only other bar they sell is a frame mount. I'm waiting to see what happens as I'm thinking of the similar kit for a 67.

Your just jealous because you can't hear the voices!

This is what I've been wanting to hear. I'll torque the top 2 down correctly and see if that lines up the others.
