I have been told that truck slant engines got the balancer bolt, others maybe not so much. I have two truck slants, both have the bolt. The only suggestion I'd add if you decide you want one, it get that bolt and washer in grade 8. I used a grade 5 in one case and even with a thick grade 5 washer, I dished the washer pretty bad cranking it down. The grade 8 washer will take all you can give it and still be laughing.
