The last time I messed with a 420, getting it out wasn't so bad. It was putting it in that caused the problem. The fella that owned the truck had ahold of it from the shifter while I was under it to start the bolt in the bellhousing. Well, to make it short, the cheap floor jack that we were using to support it let go, and I took the brunt of holding it up and shoving it in. I don't want to do that again.
