Mini-spools do have cross pins un like a full spool they just replace the spider gears and the side gears, I've run them in ford nine inch circle track racing, and I did break cross pins. but thanks for the good advice. I called trailtough to day and talked with them for about an hour and I think I'm going to go SAS, if I can find the axels, on the other hand just a question but has any one ever thought of swaping in full toyota ifs, and rear toyota solid?
I know where there is a rolled 4runner I could get for like $100
hit me up and let me know what'cha think
