And, why stop there?
After all that, there was another issue to be sorted.
I don't know why, but for some reason my rear swaybar won't fit. The crossmember interferes with it. This is documented earlier in the build. I decided to defer that project and the deferment is due. I installed some long bolts and let the mounts hang, then threaded the swaybar through and tightened them up until there was minimal clearance with no interference. This yielded a .625 inch gap.
A friend of mine just acquired a Grizzly mill and this seemed like an excellent first project for it. I already had a 1.5"x1.5"x5' bar of 6160 Al stock.
So, we set off.
Here's the process and results in images.
I'll install it tomorrow and post a picture. Next weekend is the AC installation hopefully.
