Re: 68-72 frame - shock hole measurement
Tonight I pulled out my entire rear end and suspension and started prepping to install all the new UMI parts.
The first thing I did was attempt to put in the UMI shock tower brace.
Mine was the right length and the holes lined up perfectly, and it would normally be an easy install.
But, I'm not putting it in right now for another reason - my car still has all the factory evaporation control lines coming from the gas tank, and also the fuel line and the vapor return line run right along the top of the shock towers in the rear where the shock tower brace would go, and I didn't want to tempt fate and try to move the lines out of the way and turn an easy rear suspension job into what would surely become a multi week long nightmare of replacing lines that would surely snap if I try bending them as much as they need to go to be out of the way, and then as everyone knows that would lead to a full frame off restoration because like potato chips, you can't just stop at one.
So, for now, no shock tower brace for me right now (someday in the future when I have nothing better to do and feel like getting into that mess...) but just wanted to provide the feedback that in my case, it was all the right dimensions.
