That thick-shank bolt might be a good idea considering how one has to over-torque the bolts to keep the JKS bar happy.
In billzcat1-related news....
I installed a new PS cooler and all new return hoses as well as yet another new o-ring on a good OEM pump. I took extra care to ensure I didn't overfill the system... and she still leaks from the O-ring between pump and reservoir. Not nearly as bad as before, but bad enough that I'm not happy. It looks like when I'm installing the o-ring it is getting a little crooked as the hammer-on clamps affix the reservoir to the pump. I'll have to try again.
I have a camping trip coming in 2 weeks, heading to Neah Bay/Cape Flattery - the northwestern-most point of the 48 states. Tip of the country! But since our family has grown a bit since last time we camped, I am pressed for room in the Jeep. Several pages back I entertained a larger vehicle but for the moment we've decided to keep what we've got and see if we can make it work. So for Xmas I got the Harbor Freight hitch-mounted cargo basket (which I love)... the only issue there is that it hinders access to the liftgate area and big stuff might occlude the taillights.
So I also picked up a Rola basket with the center extension. Ordered yesterday, shipped today, be here on Friday! Quick turnaround! I ordered from www.ecustomhitch.com
and they seemed to have the best price I could find. $144 for the normal Rola with free shipping, $72 for the extension, also free shipping. Can't beat that with a stick!
My garage door is kind of low so I am going to look at mounting alternatives instead of using the roof rack cross bars.
