Anybody know the difference in length between the automatic used in an 86 4by versus the manual used in the same year? If I convert to a newer tranny in place of my L43 I'm gonna hafta have the driveshafts lengthened/shortened, but I just remembered I have both drivelines from an automatic xcab, and it should have nearly the same wheelbase as my 80 longbed I believe, which would help make a cheaper conversion if they'll work, Nate
