Front Sway Bar Bushing Mount Width

Does anyone have a way to get the distance between front sway bar bushings (let's say the center of the bolt hole to the center of the bolt hole, or if you have something else just specify what it is so I can work off that)? Can you crawl under your car and measure, have a wonderbar (factory or otherwise) sitting around that you can measure? A factory body manual spec? Anything would be appreciated.

Back story- I'm trying to get the front suspension and mods reassembled (pretty much everything under the front end is new/aftermarket or made by me) and am at getting things like the sway bar, steering and brake lines hooked up and it can be tried, but I went to bolt on the sway bar and the aftermarket wonderbar (I believe that it's a '90's vintage Global West bar, but the original powder coat and logo have long come off) just won't line up. I was under it with my 11y/o son trying to get it bolted up and thought that he just wasn't strong enough to keep things in position long enough to get it assembled, so I found some m10x1.5 metric studs and decided "Hey, I can just slide all the parts over the studs and use them to line things up," and then learned tonight that nothing lines up. It looks like the frame rail mounts are about 1/4" - 1/2" too far apart to work (the holes in the wonderbar are oversized so exactly how much is hard to tell).

I'm trying to find an exact number so I can figure out what I need to fix, whether somehow my frame rails spread when I put the K-member in, somewhat hard to believe considering that these mounts are only a couple of inches from the front core support that has never been touched on this car and is welded in top and bottom, or this wonderbar has the holes in the wrong place (I don't know for sure, but if it's the GW piece that I think it is, well GW was pretty finicky about their tolerances and if it's the one I'm thinking of it's been on 3 other cars without problems, pointing towards a problem with my TA). One way I'm going to be looking to see if I can bend the frame back where it should be, the other I just need to open up the holes a little or get a different wonderbar.

Re: Front Sway Bar Bushing Mount Width

Well I still haven't found a dimension to check (anyone?), but if it's the GW bar I believe it is, it was bought for my '83 TA in about '91, I'm trying to install it on my '87, and I just ran across this scouring the old threads:

Obviously, the TDS bar has a superior mounting system, but the TDS didn't yet exist back when I bought my GW bar. I did have to do a little grinding on the mounting holes on mine, and I have no idea if it was due to bad design/manufacturing, or if I somehow got the wrong option for my '83. It was 18 years ago...
I could have sworn I had this one installed on this '87 TA or my '87 Formula 350 at one point...
