if i remember correctly that was true .i had to contact warden years ago to ask them about the degrees they reccommended it was missing from the article,
i don't no why it seemed to be a secret ? they didn't have any problem telling me .
i had to ask them about the pipe cutter thingy also ,
it did not work for me .it just broke the blades as it wobbled around the axle tube. ,
i guess i didn't grind it round enough or used the wrong type of pipe cutter ..
Also interesting who wrote that article. Harald is still around guiding people through the Rubicon. I usually run into him once a year or so but didn't see him last year. He rents clients an FJ40(he has 2), and he guides them through in his Jeep TJ.
If I had to hazard a guess, I'd guess that Dave Frieberger wrote the article. He wrote the article for SU on the first Rubithon in '89. Big Mike told me at Rubithon last year he was gonna post that one up on Marlin's website. Don't know if he ever did. I can ask him in a few weeks in Bakersfield. Or you techy guys can sleuth it out.
