Hello, I've read threw 77 pages of this.. I Have a 17 Regular Silverado 4.3 v6 .. I think I have made my mind up on what kit to install Its either Between DJM or mcgaughys ..I want to do a 3/5 with 22" .. Ive read about shims cutting drive shafts . I want to get everything all at once and be done with it and it be perfect and not have to screw with it.. I use to be into this Hobby 15 years ago but it seems that a lot of things have changed! I know everyone will have a different opinions on this subject . But just need some help! Thanks!
