If you can swing it and are going to install new engine oil cooler lines, install an engine oil bypass filter.
I install a T in the return line brother engine oil cooler to supply the bypass filter and return to the engine oil fill neck
If somebody, not in the know reads this thread the battery bolt mod requires 3/8-16 thread bolts or Allen screws.
If you use an Allen screw, it has to be flat on the ends. I like stainless or brass.
I haven't had issues mixmatching those metals. I usually use grade 8 nuts on.a stainless Allen...
I never had an issue with the side posts.
I run group 34/78 dt, Dual Terminals
I've always used -1-1/4" long Allen screws for the battery bolt mod. Make sure the screws are flat ended. Pointy screws will strip.

I ordered 2 or 3 sets of junk front wheel bearings from them. For the K1500s and K2500s.

I don't know if it helps, if it's just imagination or if it's just snake oil.
