First of all thanks again for tippin' me before I went into this.
So I had to puzzle a bit how to organize the wires around , and I actually found that it's kind of "better" to use the medium length wires for No.1 and No.6, mostly because of the angled L-shaped boots on them. I've found that straight boot is sort of hard to place and remove in that location, especially No1 , that is under the radiator hose.
And the longest went for 2 and 5, the shortest - for 2 and 4.
I've made the photo and numered everything there, just to clear all this up for somebody who may read this thread for the first time and to avoid potential confusion

Sparkplugs!
So now I've got Autolite 985 plugs in, that's what they had at local NAPA. So far so good. Started right on, was warming up sort of the same as was before. Took the jeep on the road, everything sounds and feels fine. I'll have to see how it goes later.

My old plugs were Chempion RC12LYC ..uhhhhh
I've made pics close ups. Guys, would you please take a look at them. What do you think?
I looked at Haynes "Common Sparks Conditions" chart, nothing there looks like what I have. From the first look at them - the first thought comes to mind - RUSTY!!!! heh heh ... It's redish coating stuff for the most, not sure if it's rust or what ???? Also, there is some carbon (?) black build up, if you look really close ....
Any idea on how to interprete this condition? Or is it a "type" of normal condition for an engine over 200K ???
Thanks again, guys
